摘要：
Er3+/Yb3+ co-doped TeO2-ZnO-Bi2O3 tellurite glasses were first prepared by melt-quenching method. Through precipitation of Zn2Te3O8 micro-crystals by heat treatment and introduction 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. © 2018, Science Press.
