摘要
Mn^(4+)激活的红色荧光粉具有宽带吸收、窄带发射、色纯度高以及成本低的特点,在白光发光二极管(Light emitting diode,LED)室内照明、农业上辅助植物生长、背光显示等领域的研究备受关注。本文综述了Mn^(4+)激活的典型LED用红色荧光粉研究进展。首先讨论了Mn^(4+)发光的晶体场理论,归纳了近来报道的Mn^(4+)激活氟化物与铝酸盐荧光粉;然后总结了如何从机理上优化光谱学性能、改善热猝灭性能和湿化学稳定性;最后说明了尚待解决的问题并展望了未来发展趋势。
Mn^(4+)-doped red phosphors have attracted much attention in the fields of white LED indoor lighting,agricultural plant growth and backlight displaying,due to the advantages of broad-band absorption,narrow-band emission,high color purity and low cost.This work reviews recent progress of Mn^(4+) activated typical LED red phosphors.First,the crystal field theory of Mn^(4+) is discussed.Then,the research progress of Mn^(4+) activated fluorides and aluminates is summarized.Next,how to improve luminescence performance,thermal stability and moisture resistance are discussed theoretically.Finally,the main problems in the development of Mn^(4+) doped red phosphors are presented and the future trends are prospected.
