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., Eu2+ and Mn2+, 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.
