Abstract

The BaZrO3 : 0.05Bi, xEu(x = 0, 0.010, 0.025, 0.050) phosphors were prepared by using high-temperature solid-state reaction in reducing atmosphere, and their photoluminescence properties were investigated. The broadband emission peak of Bi3+ and the typical emission peaks of Eu3+ were observed in the BaZrO3 phosphors co-doped with Bi3+ and Eu3+ under 340 nm excitation. It is confirmed that energy transfer occurred between Bi3+ and Eu3+ in the BaZrO3 : Bi, Eu phosphors, and the white light BaZrO3 phosphors can be obtained through the energy transfer between Bi3+ and Eu3+.
