ION EXCHANGE-ASSISTED SURFACE PASSIVATION TOWARD HIGHLY STABLE RED-EMITTING FLUORIDE PHOSPHORS FOR LIGHT-EMITTING DIODES

Ion exchange-assisted surface passivation toward highly stable red-emitting fluoride phosphors for light-emitting diodes

Abstract A facile and environmentally friendly ion exchange-assisted surface passivation (IASP) strategy is presented for synthesizing red emitting Mn4+-activated fluoride phosphors.A substantial, pristine Mn4+-free shell layer, applied as a coating to Mn4+ doped potassium fluorosilicate K2SiF6:Mn4+ (KSFM) phosphors, enhances both water resistance
