ABSTRACT

ABSTRACT Red phosphor (Y,03:Eu) and green phosphor (Zn2SiO4:Mn) powders with a spherical shape and an average diameter of D„50 = 3.2+/-0.2um have been prepared by the technique of spray-pyrolysis and optimal post-synthetic heat treatments. The photo-luminescence of these powders under excitation in the UV-VUV are measured and compared with those of commercial phosphors used in Plasma Display Panels. Additional characterizations are presented.
