Abstract: A process for preparing a Mn+4 doped phosphor of formula I Ax[MFy|:Mn+4  I includes gradually adding a first solution to a second solution and periodically discharging the product liquor from the reactor while volume of the product liquor in the reactor remains constant; wherein A is Li, Na, K, Rb, Cs, 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; x is the absolute value of the charge of the [MFy] ion; and y is 5, 6 or 7. The first solution includes a source of M and HF and the second solution includes a source of Mn to a reactor in the presence of a source of A.

Abstract: Fluorescent lamps that utilize mercury, and methods and materials to reduce the solubility of mercury when fluorescent lamps are disposed of in a landfill. Such a fluorescent lamp includes a transparent envelope and at least one base enclosing an interior chamber within the envelope. The base has an interior surface and a sealing portion sealed to the envelope with a cement. A gas mixture comprising mercury vapor is contained within the interior chamber, and a quantity of material is disposed on the interior surface of the base. The quantity of material is spaced apart from the sealing portion and the cement thereof, and comprises a chemical agent that substantially reduces or prevents formation of leachable mercury.
