(Ca 1− x ,Zn x )TiO 3 :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 H 3 BO 3 flux. For the CaTiO 3 :Pr phosphor, a pure perovksite‐type CaTiO 3 phase was formed when the sintering temperature was 700°–800°C. It was found that the substitution of Zn atoms instead of Ca considerably enhanced the 614‐nm red emissions. The PL intensity of (Ca 1− x ,Zn x )TiO 3 :Pr phosphor was also additionally improved by adding an H 3 BO 3 flux. Finally, the optimized phosphor Ca 0.85 Zn 0.15 TiO 3 :0.001Pr,0.1B showed the highest PL intensity.
