Abstract
Phosphors activated with Mn4+ ion are gaining prominence in the field of solid-state lighting as generators of red photon. In the present review, we focus on several important points that are fundamentally important to produce a commercially useful phosphor. This includes an understanding of the Mn4+ energy levels in the free state and in the crystal fields and of the host dependent variations in the Mn4+ emission wavelength. Additionally, we formulate several practical recommendations on how to tune the emission wavelength and emission intensity of Mn4+-doped phosphors. The main spectroscopic parameters of the Mn4+ ion in more than 100 phosphor materials are collected and discussed.
