Abstract

New phosphors with various emission colors for RE³⁺ doped Li_1+xTa_1-xTixO₃ (LTT) (RE: Eu, Sm, Er, Tm, and Dy) were synthesized by electric furnace at 1423 K for 15 h. The microstructure of the host material and the photoluminescence (PL) property were determined and compared to those of RE³⁺ doped Li_1+xNb_1-xTixO₃ (LNT). In the LTT phosphor, the highest PL intensity was achieved for the mixture composition Li_1.11Ta_0.89Ti_0.11O₃ with a LiTaO₃ structure, although it has an M-phase superstructure. In the LTT host material, the effective activators were Eu³⁺ and Sm³⁺ ions, in contrast to the LNT host material. Here, we discuss the relationship between PL property and the host material's structure.
