Abstract
There has been a growing demand for high performance nanosized oxide phosphor materials to develop novel and cost-performance flat-panel displays and all-solid-state light sources. In this study, we prepared nanosized spherical Y2O3:Eu phosphor particles by a water/oil (W/O) emulsion method using carboxymethyl cellulose ion-exchange polymer as a thickening agent and emulsion stabilizer. The phase, shape, morphology, and photoluminescence property of the obtained nanophosphor powder were examined by X-ray diffractometry (XRD), scanning electron microscopy (SEM), and fluorescence spectrometry, respectively.
