Research progress of Mn doped phosphors

In this review article, Mn applications have been divided into three parts. We provide an overview of recent progress in developing Mn4+ doped red phosphors for promising application in warm white light-emitting diodes. In addition, we summarize reports on Mn2+ co-doped Eu2+ or Ce3+ phosphors that can produce white light with outstanding color rendering index (CRI) and color coordinates via energy transfer processes, and report the application of Mn2+ in green to NIR phosphors.
