概要
- 論文の詳細を見る
Red-emitting phosphors based on gadolinium oxysulfate were synthesized in a single phase form by our original flux method using alkaline metal sulfate such as Na2SO4 and the 0.6Li2SO4--0.4Na2SO4 eutectic mixture, and photoluminescence properties were characterized. Addition of the flux is significantly effective to enhance the emission intensity, and the luminescent peak intensity of Gd2O2SO4: 10%Eu3+ increased double and triples by using Na2SO4 and 0.6Li2SO4--0.4Na2SO4, respectively. The application of the 0.6Li2SO4--0.4Na2SO4 eutectic mixture works more effectively because the melting point (600°C) is significantly lower than that of Na2SO4 (887°C).
