采用高温固相法制备了Ca4-xY5.95 (SiO4)6F2:0.05Ce3+, xMn2 +系列荧光粉,并对其发光性质以及Ce3+, Mn2 +在Ca4Y6 (SiO4)6F2 (CYSF)基质中的能量传递过程进行了研究.相结构研究表明: CYSF属于一种基于磷灰石结构的类质同象化合物.CYSF: 0.05Ce3+, xMn2+荧光粉在200–373 nm为宽带激发光谱,Ce3+和Mn2+在408 nm和602 nm的发射峰分别由Ce3+的5d→4f的跃迁和Mn2+的4T1 (4G)→ 6A1 (6S)的跃迁产生.光谱重叠现象以及荧光寿命测试结果证明了Ce3+对Mn2+具有敏化作用,能级结构分析进一步证实该体系中存在Ce3+→Mn2+的能量传递过程,可有效地将Ce3+的蓝光转换为红橙光.In this paper, a series of Ca4-xY5.95 (SiO4)6F2: 0.05Ce3+, xMn2+ phosphors with an apatite structure were synthesized by the high-temperature solid phase method; their photoluminescence properties and energy transfer behavior were investigated. The obtained phosphors exhibit a broad excitation band ranging from 200 to 375 nm and also broad emission bands with two peaks centered at 408 and 602 nm monitored at 325 nm excitation, which originate from 5d→4f transition of Ce3+ and 4T1 (4G)→6A1 (6S) transition of Mn2+, respectively. The energy transfer from Ce3+ to Mn2+ was confirmed by spectral overlap phenomenon and decay curve measurements. Based on the analysis of the energy level structure of Ce3+and Mn2+, the existence of the energy transfer from Ce3+→Mn2+ was further confirmed.
