摘要/Abstract

摘要： 利用高温固相法合成了CaSiO₃∶Eu^３＋荧光粉，确定其最佳的合成条件为：烧结温度1　200　℃；烧结时间3　h；助熔剂用量3％；激活剂的配比为2％（摩尔分数）. 对合成样品进行了荧光光谱分析，结果表明, 该荧光粉的光谱中609　nm处出现很强的发射峰，归属为Eu^３＋⁵D₀→⁷F₂跃迁发射.

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 ⁵D₀→⁷F₂ transition of Eu^３＋.

Key words: phosphor powder, calcium bisilicate, Eu^３＋, spectral characteristics
