Abstract
Y2O3:Eu red phosphor powder was synthesized with powders of metal-ethylenediaminetetraacetic acid (EDTA) complexes as a starting material. The compositional analysis of each metal-EDTA complexes particle and Y2O3:Eu particle was performed using a particle analyzer. In this study, first, the particles of a mixture of Y- and Eu-EDTA complexes were obtained by a spray drying method from solution consisting of Y- and Eu-EDTA·NH4. Then, the metal-EDTA complex powder was fired in obtaining the Y2O3:Eu red phosphor. The metal composition of each particle was scattered for the powder of the metal-EDTA mixture, while it became narrow for the Y2O3:Eu powder. The intensity of cathodoluminescence obtained from the Y2O3:Eu powder increased with increasing the fired temperature. In addition, the maximum intensity was obtained from the sample with x=0.12 for Y2âxO3:Eux.
