Introduction of metallic nanoparticles into glasses can obviously improve the up-conversion luminescence efficiency through surface plasmon resonance (SPR). In this research, the Er3+/Yb3+ co-doped TeO2-ZnO-Bi2O3 glasses containing silver nanoparticles and nanocrystals were prepared by direct current(DC) electric field assisted heat treatment, to study the effect of silver nanoparticles on the up-conversion luminescence properties of Er3+. The results show that, although the introduction of AgNO3 will weaken the thermal stability of TZB-ErYb to some extent, the number and size of silver nanoparticles can be increased after DC electric field treated at 100°C for 10 minutes. Meanwhile, the nanocrystals do not grow too large to affect the up-conversion emission intensity of Er3+. The up-conversion emission intensity of Er3+ in TZB-ErYb-6AgNO3-100°C-150V-10min is 43 times stronger than that of TZB-ErYb. These results indicate that DC electric field assisted heat treatment can synergistically adjust the silver nanoparticles and nanocrystals and is a promising method to improve the luminescence properties of tellurite glasses.
