The zinc silicate phosphor particles with various compositions were prepared by the precipitation method. Particle shape of zinc silicate phosphor have been controlled by the pyrolysis, resulting in the uniform size of spherical particles of zinc silicate phosphor. Preparation method and characteristics of this phosphor with spherical particle shape have been described. The photoluminescence and crystalline properties of green emitting phosphors were studied as a function of the firing temperature and the concentration of Mn activator.
