摘要

采用沉淀法制备了不同Sm3+掺杂浓度的白钨矿结构CaWO4荧光粉材料. 对CaWO4:Sm3+ 材料的光致发光性质的研究结果表明, 在404 nm光照下样品可以实现色纯度较高的红光发射, 而短波紫外240 nm光照下除Sm3+的特征发射外还能观察到CaWO4自激发发射, 能够获得较强的白光; 实验发现Sm3+掺杂浓度为2%时样品的发光强度最高; 通过对实验数据的分析确定了Sm3+之间的能量传递类型为电偶极-电偶极相互作用, 并计算了能量传递的临界距离大约为2.0 nm.

Abstract

The scheelite-structured CaWO4 phosphors doped with different concentrations of Sm3+ were prepared by precipitation method. Photoluminescence properties of Sm3+-doped CaWO4 samples were studied. Results indicate that red light emission of Sm3+ with higher color purity in the samples can be excited by 404 nm blue light. There are 4f-4f intrinsic emission of Sm3+ and a strong self-excitation emission of CaWO4 when excited by 240 nm short-wave ultraviolet, and the white light emission can be obtained. Experiments show that the best Sm3+ doping concentration is 2%. The energy transfer type between Sm3+ ions was determined to be the electric dipole-electric dipole interaction and the critical energy transfer distance (Dc) was calculated to be 2.0 nm.
