The Synthesis of Fine Particle Yttrium Vanadate Phosphors from Spherical Powder Precursors Using Urea Precipitation

Abstract

Spherical precursors to phosphors are reported that lead to fired materials of 1–5 μm in size with the majority of particles below 4 μm. The photoluminescence performance of the phosphors prepared by this method is as good as those of commercial phosphors, where the average size particle has a volume nine times greater than those reported here. The excitation and emission spectra for are presented. The origins of the emission in are briefly discussed. © 2000 The Electrochemical Society. All rights reserved.
