- 論文の詳細を見る
Vanadium peroxo-citrate complex was used for the first time for synthesis of YVO_4: Eu red emission phosphor material by hydrothermal method. It was found that particles size can be efficiently controlled in the range of 60-400nm by changing concentration of the solution utilized for the hydrothermal process. The nanocrystalline powders of YVO_4: Eu prepared at 200℃ for 2h with post-synthesis heat treatment at 1000℃ exhibited high fluorescence intensity comparable or better than one of the best commercially available YVO_4: Eu phosphor synthesized by conventional solid state reaction method and having much larger grain size.
