Er3+/Yb3+co-doped TeO2-ZnO-Bi2O3tellurite glasses were first prepared by melt-quenching method. Through precipitation of Zn2Te3O8micro-crystals by heat treatment and introduc-tion of Ag nanocrystals respectively,the luminescence properties of glasses are improved. However, after further heat treatment, the luminescence properties of glasses with Ag nanocrystals decrease. As Ag nanocrystals can lead to excessive crystallization of glasses during heat treatment process,the auxiliary electric field heat treatment method is applied to control the precipitation of Ag nanocrystals and micro-crystals. After auxiliary electric field heat treatment, more Ag nanocrystals are produced and the growth of micro-crystals is controlled,which lead to the improved luminescence properties of glasses.%采用熔融退火法制备得到Er3+/Yb3+共掺的TeO2-ZnO-Bi2O3玻璃.通过热处理微晶化析出Zn2Te3O8等微晶和引入Ag纳米晶这两种方式,玻璃的发光性能均有所提升.然而,对含Ag纳米晶玻璃进一步热处理后,玻璃的发光性能下降.针对银纳米晶的引入易导致热处理过程中玻璃基体过度析晶的问题,进一步采用电场辅助热处理方法来控制Ag纳米晶与微晶的析出.对含Ag纳米晶玻璃进行电场辅助热处理后,Ag纳米晶析出量增多且微晶没有过度生长,玻璃的发光性能得到进一步提升.
