Abstract
EuGa2S4 and CaGa2S4:Ce were prepared by a method of the decomposition of metal dimethyldithiocarbamates which provides a simple and safe tec hnique desired for the phosphor production. W-irradiation of such EuGa 2S4 and CaGa2S4:Ce (in the Ce/Ca=1/20 ratio) polycrystallines gave gre en and blue emission with high yield, as exemplified by relative yield s of 0.17 and 0.84 against a commercially available Y2SiO5:Ce blue pho sphor at room temperature respectively.
