Exploitable results Rare earth oxide luminescent powders More reactive rare earth oxide powders with improved morphology and a reduced level of those impurities which have a detrimental effect on the luminescent performance were investigated. These improved rare earth oxide powders will be used to develop a process for the preparation of more efficient luminescent powders with a narrower particle size distribution.
