摘要
白光发光二极管因其节能、环保、高效等特性,在照明和显示等领域具有广泛的应用.一直以来,获得具有低色温(CCT=2 700～4 500 K)、高显色指数(CRI,Ra＞80)、节约成本且适宜人眼的暖白光发光二极管是该领域研究者不懈的追求.其中红色荧光粉在高显色性能荧光粉转换型白光发光二极管器件中发挥重大作用,其研究与开发具有重要意义.概述了近年来Mn4+掺杂氟化物红色荧光粉的研究进展,主要介绍了该类荧光粉材料的常规和绿色制备方法,针对Mn4+掺杂氟化物红色荧光粉耐湿性能较差的特点,对其改性的相关报道进行了总结归纳.最后,对此类荧光粉所面临的问题进行了分析展望.
Abstract
White light emitting diodes have great advantages over traditional light sources owe to their energy-saving,environmental protection,high efficiency,and so on,which have a wide range of applications in indoor lighting,outdoor lighting,automotive lamps and electronic backlighting devices.It is always the unremitting pursuit of researchers in this field to obtain warm white light emitting diodes with low correlated color tempera-ture(CCT=2 700-4 500 K),high color rendering index(CRI,Ra＞80),cost saving and suitable for human eyes.Red phosphor can effectively improve the shortcomings and enhance the luminescent performance of such devices,which plays an important role in high color rendering phosphor-converted white light emitting diodes.Therefore,its research and development is of great significance.In this paper,the research progress of Mn4+-doped fluoride red phosphor in recent years was reviewed,and the conventional and green preparation methods of this phosphor were introduced.In terms of the poor moisture stability of Mn4+-doped fluoride red phosphor,relevant studies on improving its moisture-resistance property were summarized.Prospectively,this review con-cludes with a brief view of potential challenges and future development directions of high-performance Mn4+doped fluoride phosphor.
