Abstract

The goal of this work is to synthesize Y₂O₃:Eu⁺³ of small size and high luminous efficiency using the oxalate co-precipitation process. We find that pH, solution temperature, and calcining temperature determine particle size and morphology. Particles with the smallest mean diameter form at a pH of 4, solution temperature of 22°C, and a calcining temperature of 1000°C. Cubic and plate-let/rod-shaped particles precipitate at a high pH and irregularly shaped particles at a low pH. Powders with 2-3 mol% Eu produce the most efficient luminescence. Efficiency increases with calcining temperate as does mean crystallite size.
