Synthesis of nanocrystalline YVO4: Eu red emission phosphor with high fluorescence intensity by hydrothermal method using original vanadium-peroxo-citrate complex
Vanadium peroxo-citrate complex was used for the first time for synthesis of YVO4:Eu red emission phosphor material by hydrothermal method. It was found that particles size can be efficiently controlled in the range of 60-400 nm by changing concentration of the solution utilized for the hydrothermal...

| Summary: | Vanadium peroxo-citrate complex was used for the first time for synthesis of YVO4:Eu red emission phosphor material by hydrothermal method. It was found that particles size can be efficiently controlled in the range of 60-400 nm by changing concentration of the solution utilized for the hydrothermal process. The nanocrystalline powders of YVO4:Eu prepared at 200°C for 2 h with post-synthesis heat treatment at 1000°C exhibited high fluorescence intensity comparable or better than one of the best commercially available YVO4:Eu phosphor synthesized by conventional solid state reaction method and having much larger grain size. © 2009 The Ceramic Society of Japan.
