Title: Optimized photoluminescence of red phosphor K 2 TiF 6 :Mn 4+ synthesized at room temperature and its formation mechanism

Abstract

The formation mechanism for red phosphors K 2TiF 6:Mn 4+synthesized at room temperature has been discussed. The luminescence intensity has been improved by optimizing the synthetic process. Encapsulation of the red phosphor K 2TiF 6:Mn 4+with YAG:Ce on a GaN layer produces “warm” white LEDs with color rendering 86 at 3251 K.
