Abstract

In this paper, a new technique has been adopted for synthesis of nanophosphor particles of $Y_2O_3:Eu$ at low temperature. The optical properties of the prepared nanophosphor particles have been measured and the results have been compared with the properties of its bulk phosphor particles. The particle sizes of $Y_2O_3:Eu$ nanophosphor powder with doped-Eu concentration of 10wt% synthesized by our procedure is about 40nm. When the concentration of Eu was 10wt%, intensity of PL appeared the highest and 95% efficient as compared with bulk phosphor.
