Abstract:

The near-infrared emitting materials have been widely used in portable near-infrared spectroscopy,solar cells,optical communication,environmental monitoring,etc.They mainly include phosphors doped with transition metal ions such as Cr3+,phosphors doped with rare earth ions such as Yb3+ and Eu2+,and semiconductor quantum dots such as Ag2S and PbS.Based on the above classification,this paper introduces the research progress of near-infrared emitting materials in recent years.

Key words: phosphor  transition metal ions  rare earth ions  near-infrared luminescence  semiconductor quantum dots
