Abstract(in English) Homogeneously europium doped yttrium oxysulfide (Y_2O_2S:Eu^<3+>) red phosphor with fine grains has been synthesized from a mono dispersed sub micron size yttrium-europium hydroxy carbonate precursor, using sodium thio-sulphate as sulfiding flux. The materials synthesized have been characterized by powder x-ray diffraction, photoluminescence emission spectroscopy and scanning electron microscopy. Phase purity, morphology, and grain sizes of phosphor powders depend on the flux composition and the calcination temperature. The result indicates that grain size distribution of the phosphor materials is retaining the grain size of starting material at low temperature and increase at high temperature.
