Abstract

Greenish-white emitting Rb_1-xEr_xVO₃ (0 ≤ x ≤ 0.10) phosphors were synthesized by a conventional solid state reaction method. The thermal quenching effect of the RbVO₃ phosphors was effectively improved by Er³⁺ doping into the RbVO₃ lattice. Consequently, the emission peak intensity of the phosphors was successfully enhanced by Er³⁺ doping, and the internal quantum efficiency of Rb_0.99Er_0.01VO₃ under excitation at 360 nm was 80%.
