| description | A process for preparing color stable Mn +4 doped phosphors includes providing a phosphor of formula I;
A x [MF y ]:Mn +4 I
and contacting the phosphor in particulate form with a saturated solution of a composition of formula II in aqueous hydrofluoric acid;
A x [MF y ];II
wherein
A is Li, Na, K, Rb, Cs, NR 4 or a combination thereof;
M is Si, Ge, Sn, Ti, Zr, Al, Ga, In, Sc, 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 [MF y ] ion; and
y is 5, 6 or 7.
In particular embodiments, M is Si, Ge, Sn, Ti, Zr, or a combination thereof. A lighting apparatus capable of emitting white light includes a semiconductor light source; and a phosphor composition radiationally coupled to the light source, and which includes a color stable Mn +4 doped phosphor. |
