Y2O3，Y2O2S phosphors doped with rare earth synthesized by a citric acid gel method as a liquid phase reaction have been investigated.The advantages of liquid phase reaction synthesis are a low firing temperature, uniformly doped materials and fine-particle powders.The phosphors obtained by this method showed good uniformly luminescent centers and good crystallinity and luminescence characteristics at a firing temperature of 1000°C.Moreover, we obtained particles smaller than 1μm.It is expected that a liquid phase reaction will be a conventional method of synthesizing phosphors in the future.
