Abstract: A phosphor composition is derived from combining K2SiF6:Mn4+ in solid form with a saturated solution of a manganese-free complex fluoride including a composition of formula I:A3[MF6], where A is selected from Na, K, Rb, and combinations thereof; and M is selected from Al, Ga, In, Sc, Y, Gd, and combinations thereof. The composition of formula I:A3[MF6] has a water solubility lower than a water solubility of K2SiF6. A lighting apparatus including the phosphor composition is also provided. Fig. 3
