Abstract: A coated phosphors that include a shell comprising a first Mn4+doped phosphor of formula (I) Ax [MF y ]:Mn 4+ directly disposed on a core comprising a second phosphor. The second phosphor is a material other than a compound of formula (I) or formula (II) A x [MF y ]wherein A is, independently at each occurrence, Li, Na, K, Rb, Cs, or a combination thereof; M is, independently at each occurrence, Si, Ge, Sn, Ti, Zr, Al, Ga, In, Sc, Hf, Y, La, Nb, Ta, Bi, Gd, or a combination thereof; x is the absolute value of the charge of the [MFy] ion; and y is 5, 6 or 7.
