近年来,单体白色荧光粉,尤其是基于能量传递原理构建的白色荧光粉成为发光领域的研究热点。简要评述了近5年紫外一近紫外基白光LEDs用单体白色荧光粉的研究进展。重点阐述了单掺杂体系,以及基于能量传递原理构建的双掺杂及三掺杂等单体白色荧光粉的研究结果与最新进展;同时,分析和预测了该类材料的研究前景及发展方向。
Recent work have focused on the development of single white emitting phosphor, in particular, based on the principle of energy transfer. This review represents the development on single white phosphor for white light emitting diodes during the past 5 years. The topic emphasized the co-activated and tri-activated white emitting phosphors obtained by the energy transfer from the sensitizer to acceptor. Moreover, the research prospect and future development of this material were discussed.
