Abstract

Green light emitting (Ba,Sr)₂SiO₄:Eu phosphor particles with high photoluminescence intensity under long wavelength ultraviolet (UV) were prepared by spray pyrolysis from colloidal spray solution. Yttrium, cerium and holmium components were introduced as co-doping materials to improve the photoluminescence characteristics of (Ba,Sr)₂SiO ₄:Eu phosphor particles in the spray pyrolysis. The photoluminescence intensities of co-doped (Ba,Sr)₂SiO₄:Eu phosphor particles were about 120∼143% of (Ba,Sr)₂SiO₄:Eu phosphor particles without co-dopant. The highest photoluminescence intensity was achieved when the doping concentration of yttrium was about 1.7 times of the doping concentration of europium. The photoluminescence intensity of the sieved phosphor particles using 20 μm sieve was comparable to that of the original (Ba,Sr)₂SiO₄:Eu phosphor particles.
