摘要

La1-xEuxKNaNbO5 (x = 0.1--1), La1-xTbxKNaNbO5 (x = 0.1 --0.4) and Tb0.1La0.9-xEuxKNaNbO5 (x = 0--0.1) photoluminescent materials were successfully synthesized by a solid-state reaction. La1-xEuxKNaNbO5 (x = 0.1--1) and La1-xTbxKNaNbO5 (x = 0.1--0.4) exhibit room-temperature photoluminescence with orange-red and green emissions, respectively. In addition, the excitation and emission spectra are same as the pure EuKNaNbO5 and TbKNaNbO5 compounds. For Tb 0.1La0.9-xEuxKNaNbO5 (x = 0--0.1), as the energy can be transferred from Tb3+ to Eu3+, the color was correspondingly modified from green to yellow to orange.;Synthesize oxides by molten hydroxide fluxes is an effective method. My works have been focused on the preparation of rare-earth and transition metal containing oxides using hydroxide flux route, which has resulted in the synthesis of several oxides, namely Dy3TaO7, LaCoO 3 and LaFeO3.
