摘　　要：在背光源液晶显示(LCD)领域,窄带绿光发射荧光粉对于扩宽显示色域、提高发光强度、优化显色性能等具有重要的作用。近年来,针对LCD用窄带绿光发射荧光粉有着广泛的研究,也取得良好的进展,然而对此类荧光粉的系统性总结却鲜有报道。本文综述了近年来绿色窄带发射荧光粉的研究进展,通过对不同的激活离子进行了分类,重点介绍了以Eu^(2+)、Mn^(2+)做激活离子为代表的荧光粉,归纳分析了荧光粉结构和发光性能的关系,并阐述了各自的优缺点,同时对其未来发展前景进行了展望。In the field of backlight liquid crystal display(LCD),narrow-band green-emitting phosphor plays an important role in expanding the color gamut,improving luminous intensity and optimizing color rendering performance.This review represented recent research progress on the narrow-band green emission phosphors.The phosphors classified by different activating ions,i.e.,Eu~(2+) and Mn~(2+),were introduced,and the relationships between their structures and luminescence properties were analyzed.In addition,the advantages and disadvantages were described and the future development were also prospected.
