摘要：

(Ca1-x,Zn-x)TiO3:Pr, B red phosphor particles were prepared using the peroxide-based route and their photoluminescent (PL) properties were investigated by changing the sintering temperature, the concentration of the activator, the ratio of Ca to Zn, and the amount of H3BO3 flux. For the CaTiO3:Pr phosphor, a pure perovksite-type CaTiO3 phase was formed when the sintering temperature was 700 degrees-800 degrees C. It was found that the substitution of Zn atoms instead of Ca considerably enhanced the 614-nm red emissions. The PL intensity of (Ca1-x,Zn-x)TiO3:Pr phosphor was also additionally improved by adding an H3BO3 flux. Finally, the optimized phosphor Ca0.85Zn0.15TiO3:0.001Pr,0.1B showed the highest PL intensity.
