As a highly productive narrow-band emission red phosphor, K2SiF6:Mn4+ has towardly application market in pc-WLEDs (Phosphor-converted white light-emitting diodes) and LCD (Liquid crystal display). However, the poor moisture resistance property is recognized impediment for generalizing its wider commercialization. Herein, we adopt a simply green and convenient strategy based on Fe2+, which is committed to decreasing the reaction between luminescence center and water. The K2SiF6:Mn4+ as expected exhibits highly efficient red emission upon excitation.
