The formation mechanism for red phosphors K2TiF6:Mn4+synthesized at room temperature has been discussed. The luminescence intensity has been improved by optimizing the synthetic process. Encapsulation of the red phosphor K2TiF6:Mn4+with YAG:Ce on a GaN layer produces “warm” white LEDs with color rendering 86 at 3251 K.
