Phosphor powders with an average particle size on the order of 0.5 μm were obtained from 0.2 M aqueous solutions of the corresponding metal salts. Relative concentration of gadolinium (x) was varied in the range 0 to 1. For excitation at a wavelength of 254 nm, the highest intensity of photoluminescence was achieved for x 0.2 (110% of brightness of the samples without gadolinia). Doping pure yttria and gadolinia with nanoparticles of Y2O3:Eu (dBET 24 nm) was tested. Addition of nanoseeds (up to 50 mol.% in the obtained powders) noticeably decreased surface roughness of phosphor particles. © 2011 Ceramic Society of Japan.enPhysikPhotoluminescence of (YGd)₂O₃:Eu phosphors produced by nanoparticle-seeded flame-assisted spray pyrolysisConference Paper10.1088/1757-899X/18/10/102018Other
