Effects of In2O3 nanoparticles doping on the photoluminescent properties of Eu2+ /Eu3+ ions in silica glasses

摘要

Eu2+ /Eu3+ ions doped silica glasses contained In2O3 nanoparticles (NPs) have been fabricated by using nanoporous silica glasses. Interestingly, efficient energy transfer from In2O3 NPs to Eu2+ /Eu3+ ions enhanced the photoluminescence (PL) emission of Eu2+ /Eu3+ ions, which derives from lattice defects in In2O3 NPs. Our work has not only demonstrated a facile way to fabricate NPs and rare earth ions co-doped silica glasses, but also extended the applications of semiconductor oxide NPs such as In2O3 NPs.
