    Abstract: A process for fabricating an LED lighting apparatus comprising a color stable Mn4+ doped phosphor of formula I includes forming on a surface of an LED chip a polymer composite layer comprising a first and a second population of particles of the phosphor of formula I having a graded composition varying in manganese concentration across a thickness thereof; Ax (M, Mn) Fy (I) wherein A is Li, Na, K, Rb, Cs, NR4 or a combination thereof; M is Si, Ge, Sn, Ti, Zr, Al, Ga, In, Sc, Hf, Y, La, Nb, Ta, Bi, Gd, or a combination thereof; R is H, lower alkyl, or a combination thereof; x is the absolute value of the charge of the [MFy] ion; and y is 5, 6 or 7. The first population of particles has a lower manganese concentration than the second population of particles, and the manganese concentration in the polymer composite layer ranges from a minimum value in a region of the polymer composite layer proximate to the LED chip to a maximum value in a region opposite to the LED chip.
