The coating of phosphor in P2O5-ZnO-B2O3 glass for LED has been prepared.The powder of low-melting-point P2O5-ZnO-B2O3 glass was used as matrix,which is mixed with yttrium aluminum gamet crystals containing Ce(YAG:Ce phosphors),organic solvent(absolute ethyl alcohol)and binder(ethyl cellulose).After stirring glass,YAG:Ce phosphors,organic solvent and binder well,glass paste was made and the silk screen printer was used to print the glass paste on the glass substrate.Then this glass with coating was sintered.The microstructure of the coating was shown by the super depth of field microscope.The increase of contents of YAG:Ce were not benefit for the coating.By X-ray diffraction(XRD),crystallization behavior of the phosphor in glass coating was studied.The effects of the YAG:Ce phosphors content and sintering temperatures on luminescent properties were investigated.

采用拓扑束缚理论，在对硅磷酸盐玻璃结构的定量建模基础上，计算其玻璃转变温度和硬度值，得出组成、结构与性能的关系式，对整个三元玻璃体系的性能进行模拟，实现高性能玻璃设计。此外，通过热处理手段对硅磷酸盐玻璃结构进行调节，研究了热处理后钠硅磷玻璃的折射率和吸收光谱性能。拓扑束缚理论具有模型简单、计算准确性较高等优点，有利于新玻璃体系性能的研究和高性能玻璃的组成设计。
稀土掺杂微晶玻璃发光材料在照明、显示、固体激光及防伪等诸多领域都有着广泛的应用前景。众所周知,这些性质受玻璃材料中的纳米结构、形貌和尺寸影响很大。因此,实现在玻璃材料中纳米结构的可控合成具有十分重要的理论和现实意义。本文通过传统高温熔融方法制备硅铝酸盐玻璃,并对其玻璃的修饰体(Li、Na、K)成分比例进行调整,并通过共掺杂Er3+和yb3+离子,研究其发光性能。实验结果表明,基于能量传递机理,利用
本研究用母体杂多酸(HPA)选择饱和Keggin型磷钨酸(H3PW12O40)作为无机前驱体,四异丙氧基钛(Titanium tevaisopropoxide,TTIP)作为钛源,石英片作为基底,采用溶胶-凝胶法结合控温技术和旋涂技术,制备掺杂金属离子的磷钨酸/二氧化钛(M+/H3PW12O40/TiO2)复合膜.通过掺杂金属离子Cu、Fe、Ag以及掺杂的质量比(M+/Ti4+)分别为0.5％、1
GeS2基硫系玻璃具有极低的声子能量(～350cm-1)和较大的折射率(＞2.1),对于增强掺杂金属离子荧光发射效率极为有利.然而,GeS2基硫系玻璃短波截止边位于500nm,严重制约了这一类玻璃在可见光荧光材料方面的应用.通过引入CsC1,可显著拓展GeS2基硫系玻璃在可见光波段的透过范围,甚至实现可见光波段全透玻璃[1].以CsCl改性的GeS2基硫卤玻璃为基质,我们制备了一系列Ce3+、Eu
