Abstract: CaSiO₃∶Eu^３＋ phosphor powder was prepared by the ceramics method. The optimal synthetic conditions are that sintering temperature is 1　200　℃, sintering time is 3　h, the concentration of t he fluxing agent is 3％, molar matching of the activating agent is 2%.The fluorescence spectrum of the phosphor powder was measured. The results indicate that the emission spectrum exhibits a sharper and more effective peak at 609 nm corresponding to the ⁵ D₀→⁷F₂ transition of Eu^３＋.
