Abstract

This work demonstrates the synthesis of indium tin oxide nanocrystals (ITO NCs) in mesoporous silica glasses (MSG) via the impregnation and decomposition method. The original MSG have many uniformly distributed mesopores (5-40 nm) which can regulate and control the size and distribution of ITO NCs. Factors that affect the properties of ITO NCs including temperature and holding time have been mainly studied. Interestingly, the enhanced down-conversion fluorescence intensity of Er³⁺/Yb³⁺ ions due to the energy transfer from ITO NCs has also been observed. Our work can widen the applications of semiconductor oxides in optoelectronics with a facile way.
