Abstract
The present invention relates to a high temperature glass material changing ultraviolet rays into visible light, which belongs to the field of glass material. A water solution of cerous nitrate and aluminum nitrate or a water solution of cerous nitrate, manganese nitrate and aluminum nitrate is mixed in micropore glass with the content of SiO2 over 96%, and is sintered under a reduction condition after drying so that vycor glass containing Ce<3+> and Al<3+> or Ce<3+>, Mn<2+> and Al<3+> is manufactured, wherein the vycor glass containing Ce<3+> and Al<3+> can change the absorbed ultraviolet rays into blue light, and the vycor glass containing Ce<3+>, Mn<2+> and Al<3+> can change the absorbed ultraviolet rays into red light. The present invention is used for manufacturing high voltage xenon lamps, pulse xenon lamps, mercury xenon lamps and high voltage mercury lamps, and can change the harmful and useless ultraviolet rays into useful visible light.
Description
The invention belongs to the glass material field.
The pipe wall material that domestic and international at present manufacturing high pressure xenon lamp, xenon flash lamp, xenon-mercury lamp, high voltage mercury lamp are used is generally silica glass.But this lamp all has a large amount of useless even deleterious ultraviolet rays.High pressure xenon lamp is as cinema lamp, and the short wave ultraviolet that it sent can make airborne oxygen ozonize, and environment, projection staff health are harmful to.Xenon flash lamp is as LASER Light Source, and the short wave ultraviolet that it sent can damage working-laser material, and laser output is reduced.Xenon-mercury lamp, high voltage mercury lamp are as lighting source, and the ultraviolet ray that it sent can not directly be used.High voltage mercury lamp need add a shell that scribbles phosphor powder in addition ultraviolet ray is transformed into visible light.In order to overcome this drawback, have in recent years to adopt and mix TiO
