| Abstract: | 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. |
