摘要：
In recent years, narrow-band phosphors have attracted widespread attentions in the field of LED display due to the advantages of expanding display color gamut, improving color reproducibility and enhancing luminous efficiency. However, due to the limited number of narrow-band phosphors reported so far and the expansion effect of Eu2+ 4f-5d transition, the research and development of Eu2+-doped phosphors with narrow-bands for emerging fields still face huge challenges. This article overviews the currently reported Eu2+-activated UCr4C4 type phosphors with narrow-band emissions, describes the crystal structure characteristics, photoluminescence properties and their applications of Eu2+-doped UCr4C4-based nitrides, oxide and oxynitride phosphors, and discusses the structure-related luminescence properties. It is expected that the review could provide meaningful enlightenment for the design of novel rare earth doped emissions. © 2020, Science Press. All right reserved.
