K2SiF6:Mn4+ red-luminescent crystals with high external quantum efficiency (EQEmax of 78%) and high thermal quenching temperature (T1/2 > 500 K) enabling high brightness warm white LEDs

Mn4+-activated fluoride phosphor is one of the crucial red-emitting phosphors for white lighting systems driven by light-emitting diodes (LEDs). In this study, we successfully synthesized high-quality K2Si1-xF6:xMn4+ (x = 0.03–0.70)... Click to show full abstract
