| Abstract: | The BaZrO3 nanopowder composed of perovskite was prepared by using sol-gel combustion method under 700 ℃.Meanwhile,the products was studied on the luminescent properties with different concentrations of Eu3+ and Dy3+-doped.The results show that BaZrO3 powder exhibits good luminescent feature and the Eu3+-doped samples exhibit strong orange-red light emission between 590~630 nm.Furthermore,the luminescent density reaches the maximum value in the 5% density of Eu3+-doped.However,the Dy3+-doped sample shows strong yellow and blue light emission in 575 nm and 480 nm respectively.Moreover,the optimal density is in 1.0% Dy3+-doped with no clear density quenching. |
