Article Preview

Ca3(VO4)2: Eu3+, Bi3+ phosphor powders were prepared by the combustion synthesis or the solid state reaction at room temperature, respectively. The phase composition, morphology and photo-luminescence of the Ca3(VO4)2: Eu3+, Bi3+ phosphors were investigated by X-ray diffraction, scanning electron microscope, and spectrophotometry, respectively. The results show that the Ca3(VO4)2: Eu3+, Bi3+ powder prepared by the combustion synthesis is claviform, while the Ca3(VO4)2: Eu3+, Bi3+ powder directly obtained by the solid state reaction at room temperature is orbicular. The discrepancy in emission is attributed to the variation in the Eu3+ morphology of in powders.
