Abstract

Europium-doped Lu₂O₃ phosphors were prepared via a co-precipitation process. The influence of precipitants on morphology and dispersibility of the obtained Lu₂O₃ powders were investigated. Precipitation was performed with three different precipitants, namely ammonium hydroxide (NH₃·H₂O), ammonium hydrogen carbonate (NH₄HCO₃), and the mixture of NH₃·H₂O and NH₄HCO₃. Ultrafine, nearly monodispersed, weakly agglomerated and near-spherical lutetia powders could be obtained with mixed NH₃·H₂O and NH₄HCO₃ as the precipitant. The precipitate precursor with the mixed precipitant was believed to possess a basic carbonate composition and its thermal decomposition and phase evolution processes were investigated. Photoluminescence characteristics of Lu₂O₃:Eu³⁺ phosphors obtained by this modified precipitation method were also studied.
