Abstract
Manganese activated zinc silicate phosphors are prepared by fume pyrol ysis of metal alkoxide solution in an electric furnace heated at 950-d egrees-C. The microstructure examined by SEM shows that the particles were spherical and highly dispersed. The emission intensity of the pho sphors prepared by fume pyrolysis is stronger than that of the phospho rs produced by conventional methods. The particle size and the emissio n intensity of the phosphors were dependent on firing temperature.
