摘要：
Mn4+-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 Mn4+ activated typical LED red phosphors. First, the crystal field theory of Mn4+ is discussed. Then, the research progress of Mn4+ 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 Mn4+ doped red phosphors are presented and the future trends are prospected. © 2021, Science Press. All right reserved.
