Description
Technical field: the invention belongs to the steady persistence with memory storage function and the preparation method of light stimulus long afterglow glass and glass-ceramic.
Background technology: at present, mostly be the long afterglow glass of transmitting green twilight sunset about the report of long afterglow glass, and launch the rarely found report of long afterglow glass of red twilight sunset." the Japanese applicating physical magazine " of 1999 the 38th volume 6A/B phases delivered exercise question at L649 to L651 page or leaf and has been " the adulterated Sodium Tetraborate glass of infrared femtosecond laser inductive bivalent manganese long-persistence luminous " technology, this technology is amplified the locked mode femtosecond laser with the titanium jewel and is shone this glass after 10 seconds, remove femtosecond laser, glass has red twilight sunset phenomenon, this twilight sunset in 5 minutes naked eyes as seen, twilight sunset is shorter; And the femto-second laser power that is used for excitaton source is huge, costs an arm and a leg, and only limits to laboratory study.United States Patent (USP) 6,123,872 disclose the silicon boron system glass with steady persistence and optical stimulated luminescence phenomenon, its green long afterglow is luminous to be realized by the doping terbium sesquioxide, red long-afterglow is luminous to be realized by the doping manganese oxide, the long-persistence luminous time of glass is 1 second to two hour, and this glass does not have light stimulus steady persistence phenomenon; Its molar content that mixes manganese oxide separately is 0.1%-0.99%.Application number is 01118256.3 Chinese patent, and a kind of preparation method with redness, green, yellow longpersistent BSiZn glass is provided, but this method does not provide the preparation method of preparation light stimulus long afterglow glass.
Summary of the invention: the purpose of this invention is to provide a kind of steady persistence and light stimulus long afterglow glass and glass-ceramic with memory capability;
Another object of the present invention provides a kind of the have steady persistence of memory capability and the preparation method of light stimulus long afterglow glass and glass-ceramic.
This method is selected boron trioxide, zinc oxide, and Manganse Dioxide, yttria, silicon-dioxide, antimonous oxide are raw material, after grinding mixing, constant temperature is handled and is obtained red long-afterglow and light stimulus long afterglow glass; To this red long-afterglow with can obtain green, yellow longpersistent and light stimulus long afterglow glass pottery after the light stimulus long afterglow glass carries out different thermal treatment.The manganese oxide content that this method is used is less, when manganese oxide content more for a long time, the steady persistence of glass and light stimulus steady persistence phenomenon can weaken because of the concentration quenching under high doping of mn ion or disappear.The openworking template that is carved with literal or image is covered on glass or glass-ceramic, excite with short wave ultraviolet, X ray or gamma rays then, have only the part of hollow out to be excited so to produce long-persistence luminous; When steady persistence disappeared, with long wave ultraviolet, visible light or infrared-ray irradiation monolithic glass or glass-ceramic, literal or image can reappear, and the other parts of glass or glass-ceramic are not luminous, thereby had realized the memory storage of glass and glass-ceramic; And when long wave ultraviolet, visible light or infrared-ray disappeared, literal that reappears or image did not disappear thereupon, but exist with the form of steady persistence.Directly carry out photoetching and can deposit literal or image in glass or glass-ceramic equally with short wave ultraviolet.
The generation of steady persistence phenomenon is to cause the generation of defect level owing to mix, in excitation phase, defect level is caught hole or electronics, when excite finish after, the electronics of being captured by shallow energy level slowly discharges owing to thermal motion, d/d electronics and hole-recombination give off energy and give luminescence center with transmission ofenergy, thereby produce the steady persistence phenomenon; Under the excitation of visible light etc., the electronics in dark defect level of hiding can discharge from defective and be captured by the more shallow defect level of emptying, when exciting light stops, these electronics of being captured by secondary at room temperature since thermal motion discharge, and combine with the hole and to emit energy, thereby produce the steady persistence phenomenon of secondary emission.This when exciting light disappears, the phenomenon that optical stimulated luminescence still exists is called light stimulus steady persistence phenomenon; And concerning the optical stimulated luminescence phenomenon, along with the disappearance of exciting light, optical stimulated luminescence also disappears thereupon.The twilight sunset color of the steady persistence of glass or glass-ceramic and light stimulus steady persistence is by Mn
2+The residing coordination environment decision of ion: Mn
2+When ion was in the hexa-coordinate environment, glass twilight sunset was red, and emission peak is at 592nm; Mn
2+When ion was in the four-coordination environment, glass twilight sunset was green, and emission peak is at 520nm; As the Mn that is in four-coordination and hexa-coordinate environment
2+When ion was proportional, glass twilight sunset was yellow, and emission peak is at 560nm.In transparent glass, mn ion is in the hexa-coordinate environment, so glass emission red long-afterglow and light stimulus steady persistence; When glass being carried out different thermal treatment make it become glass-ceramic, the coordination environment of mn ion becomes four-coordination or four, hexa-coordinate coexistence according to concrete treating processes, thus glass-ceramic transmitting green or yellow longpersistent and light stimulus steady persistence.When manganese oxide content was higher in glass and the glass-ceramic, steady persistence and light stimulus steady persistence can weaken because of the concentration quenching effect of mn ion or disappear.But when the content of mn ion is very few, steady persistence and light stimulus steady persistence can become very because of the deficiency of light emitting ionic quantity a little less than.
The glass molar percentage of the present invention's preparation consists of: boron trioxide 15%-40%; Zinc oxide 40%-65%; MnO 0.005%-0.095%; Yttria 0%-0.6%; Silica 1 0%-35%; Antimonous oxide 0%-0.05%.After the glass composition ground mixing, in Reaktionsofen,, after coming out of the stove, glass metal obtains red long-afterglow and light stimulus long afterglow glass in 1250 ℃ of-1550 ℃ of constant temperature 0.5 hour-2 hours; Constant temperature between 650 ℃-750 ℃ was handled 0.5-24 hour with red long-afterglow and light stimulus long afterglow glass, obtained yellow longpersistent and light stimulus long afterglow glass pottery; Constant temperature between 750 ℃-1000 ℃ was handled 0.5-24 hour with red long-afterglow and light stimulus long afterglow glass, obtained green long afterglow and light stimulus long afterglow glass pottery.Above-mentioned thermostatic process can be to handle in process furnace, or with carbon dioxide laser glass is handled.The openworking template that is carved with literal or image is covered on glass or glass-ceramic, excite with short wave ultraviolet, X ray or gamma rays then, have only the part of hollow out to be excited so to produce long-persistence luminous; When steady persistence disappeared, with long wave ultraviolet, visible light or infrared-ray irradiation monolithic glass or glass-ceramic, literal or image can reappear, and existed with the form of steady persistence.Directly carry out photoetching and can deposit literal or image in glass or glass-ceramic equally with short wave ultraviolet.
Compare with the glass system that above-mentioned patent is described with steady persistence and optical stimulated luminescence phenomenon, glass of the present invention has following characteristics: 1, this glass does not contain terbium ion, the molar content of manganese oxide is less in the glass, be 0.005%-0.095%, avoided the concentration quenching effect of mn ion, thereby the red long-afterglow of glass is bright lasting, reaches 12 hours; 2, this glass also has the light stimulus steady persistence phenomenon different with the optical stimulated luminescence phenomenon except having the steady persistence phenomenon; 3, when glass through after different thermal treatment becomes glass-ceramic, the color of its steady persistence and light stimulus steady persistence becomes yellow or green by redness, and other active ions that do not need to mix are realized the transformation of glow color.
Red long-afterglow and light stimulus long afterglow glass with memory function of the present invention, the preparation method of yellow, green long afterglow and light stimulus long afterglow glass pottery is simple, and glass that makes and glass-ceramic have bright, persistent steady persistence and light stimulus steady persistence; Utilize light stimulus steady persistence phenomenon, can realize the memory storage function of glass of the present invention or glass-ceramic: utilize the optical stimulated luminescence phenomenon to store to compare, utilize light stimulus steady persistence phenomenon to carry out memory storage and have characteristics such as easy, directly perceived with common.Therefore, red long-afterglow and the light stimulus long afterglow glass with memory function of the present invention is the detecting material of a kind of extremely promising optical memory material and energetic ray with yellow, green long afterglow and light stimulus long afterglow glass pottery.It can be used on aspects such as information storage, energetic ray detection, Emergency Light, artistic handicraft using.
