摘要:
     白光LED具有工作电压低、功耗低、可靠性高、使用寿命长、环境友好和高能效等一系列优点，是未来照明光源的发展方向。利用LED技术实现白光的方法主要有3种，其中采用蓝光、紫光及近紫外LED芯片激发红、绿、蓝等三基色或多基色荧光粉得到白光LED的技术具有成本低、显色性好等优势，是白光LED的主要发展方向。红色荧光粉在调制白光的色温及改善其显色性等方面起重要作用，其制备技术是目前制约白光LED大规模应用的关键技术，亟待解决。详细介绍了白光LED用红色荧光粉的十余个主要材料体系的发光性能、基本制备方法、取得的研发进展，简单探讨了其未来发展趋势。
Abstract:
     White light LED is a promising future lighting source，because it has many advantages including low voltage，low power consumption，high reliability，long service life，environment friendliness, and high energy efficiency，etc. Among the three major preparation methods，the one using blue，violet and near ultraviolet LED chip to excite the trichromatic phosphor or multichromatic phosphor based on red，green and blue phosphor is nowadays an acceptable solution，which possesses low cost and better chromogenic performance. However，red emitting phosphor，the key component in adjusting the color temperature and chromogenic performance in order to get high purity white light，is actually the bottleneck obstructing large scale application of white light LED. More than ten red emitting phosphor material systems for white light LED usage，their performances，preparation processes，and recent developments are introduced in detail, and the technology trends are briefly discussed.
