Abstract

The present invention is a kind of europkium-activated alumine acid strontium long afterglow phosphor material and preparation thereof.The chemical constitution formula of this material is m (Sr 1-xEu x) OnAl 2O 3YB 2O 3, its preparation technology is as follows: press the weighing of component proportioning, porphyrize with aluminium, strontium, europium and the oxide compound of boron or the salt of corresponding above-mentioned oxide compound, in High Temperature Furnaces Heating Apparatus, heated 1-6 hour, after the cooling again at N 2+ H 2Calcination 1-4 hour promptly in the atmosphere.This material settling out performance is good, time of persistence is long, at UV-light or natural light irradiation several minutes, can reach tens to tens hours its time of persistence.The surface of relevant device or ornament be can extensively be coated on, demonstration and decoration are used at dark surrounds.

Description

Long-decay phosphor material and preparation thereof
The present invention is a kind of europkium-activated alumine acid strontium long afterglow phosphor material.
Common phosphorescent substance is used for luminescent lamp as photoluminescence material.Europkium-activated strontium aluminate phosphorescent substance is widely used in high color rendering fluorescent lamp.About europium (Eu) activated strontium aluminate phosphorescent substance SrAl 2O 4: Eu, as far back as U.S.patent 3294699(1966) on the books, be a kind of green phosphor, the emmission spectrum main peak is 520nm.J.T.C.Van kemenade and G.P.F.Hoeks, Eetended abstract No.607 E.C.S.Spring Meeting(1983) reported Sr in 4Al 14O 25: the Eu phosphorescent substance, be blue green, the emmission spectrum main peak is 490nm.The clear 61-69885 of Japanese Patent has proposed to have the phosphorescent substance of phosphorus oxide component, and chemical structural formula is 4(SrEu) OXAl 2O 5YP 2O 5, 0≤x≤8,0＜y≤0.4 wherein.The improvement of above-mentioned phosphorescent substance is all carried out for improving luminous efficiency.But also there is not this phosphorescent substance directly is coated on the surface of device or ornament, as the noctilucence display material in the dark surrounds.
Sulfide-based long-decay phosphor material is all shorter time of persistence, and unstable chemcial property easily decomposes, and practical value is less.For example ZnS:Cu or (Zncd) S:Cu long persistence phosphor time of persistence dozens of minutes only, add Co after time of persistence can extend to several hours, but infrared quencher easily takes place.Need coating to handle during such long-afterglow material practical application, use H when synthetic 2S gas causes environmental pollution.The CaS:Bi long persistence phosphor is longer time of persistence, but unstable chemcial property.
The purpose of this invention is to provide a kind of stability is good, time of persistence is long phosphor material and preparation technology and practical application.
The long-decay phosphor material that the present invention proposes contains element components such as strontium, europium, aluminium, in addition, also contains the boron oxide component, and its chemical constitution is:
m（Sr1-x Eux）O·nAl 2O 3·yB 2O 3
Each coefficient scope is: 1≤m≤5,1≤n≤8,0.001≤x≤0.1,0.005≤y≤0.35
The preparation technology of above-mentioned long-decay phosphor material is as follows: starting material adopt the oxide compound of aluminium, strontium, europium and boron, perhaps the salt of the above-mentioned oxide compound of the corresponding generation of energy after heating.For example, oxyhydroxide, carbonate, nitrate etc.These compounds are pressed the ratio range weighing of each element components in the phosphor material chemical constitution, grind to form smalls, uniform mixing.Produce as follows then: with said mixture in 1200-1600 ℃ of High Temperature Furnaces Heating Apparatus calcination 1-6 hour, took out the cooling back, pulverizes, again at 1000-1400 ℃ N 2+ H 2Reduction calcination 1-4 hour promptly in the atmosphere.Also can be with said mixture directly at N 2+ H 2Calcination keeps making in 1-5 hour to 1200-1600 ℃ in the atmosphere.
By the long-decay phosphor material of above-mentioned prepared, be yellow-green colour or blue green, under ultraviolet excitation, the emmission spectrum main peak is at 500-520nm.This phosphor material stable performance behind UV-light or natural light irradiation, has very long time of persistence.After generally shining several minutes in natural light, all the other radiance times are tens hours to tens hours.
Utilize the stability and the long afterglow property of above-mentioned phosphor material, it can be coated on the surface of some devices or ornament, for example surfaces such as instrument, clock and watch, plastics, ceramic utensil, workmanship behind UV-light or natural light irradiation, are used for demonstration and decoration at dark surrounds.
Embodiment 1, get Al(OH) 3: 11.14 grams, Eu 2O 3: 0.21 gram, SrCO 3: 6.05 grams, H 3BO 3: 0.185 gram, these compounds are ground to form smalls, uniform mixing, calcination is 3 hours in 1500 ℃ High Temperature Furnaces Heating Apparatus, and the cooling back is taken out and is pulverized, again at N 2+ H 2Be heated to 1200 ℃ in the atmosphere, kept 1-4 hour, promptly get long-decay phosphor material, the coefficient of its chemical constitution is respectively: m=4, and n=7, x=0.03, y=0.15, emmission spectrum main peak are 500nm.This phosphor material is used to be coated in instrument or clock face, or the surface of other ornaments, and behind the natural light irradiation several minutes, be about 20 hours its time of persistence.
Embodiment 2, get Al(OH) 3: 79.6 grams, Eu 2O 3: 2.6 grams, SrCO 3: 71.6 gram and H 3BO 3: 0.618 gram, with the levigate uniform mixing of these compounds, calcination is 3 hours in 1500 ℃ High Temperature Furnaces Heating Apparatus, and the cooling back is taken out and is pulverized, again at N 2+ H 2Be heated to 1200 ℃ in the atmosphere, kept 3 hours, promptly get long-decay phosphor material, emission peak wavelength 520nm, the coefficient of its chemical constitution formula is: m=1, n=1, x=0.03, y=0.01.Time of persistence was greater than 10 hours.
