Abstract: A method includes mixing a first fluoride phosphor powder that is doped with tetravalent manganese with a treatment solution for a designated period of time, stopping the mixing to allow the fluoride phosphor powder to settle, removing at least some liquid that has separated from the first fluoride phosphor powder, repeating (a) the mixing, (b) the stopping of the mixing, and (c) removing at least some of the liquid during one or more additional cycles, and obtaining a second fluoride phosphor powder following the repeating of the mixing, the stopping of the mixing, and the removing of at least some of the liquid. The second fluoride phosphor powder includes a reduced amount of the manganese relative to the first fluoride phosphor powder.

Abstract: Coating systems suitable for use in fluorescent lamps, particularly as scattering agents within a UV-reflecting coating for the purpose of improving fluorescent lamp luminosity. Such a coating system is provided on a transparent or translucent substrate and includes a phosphor coating and a scattering agent that scatters UV rays. The scattering agent includes an inorganic powder present in a separate UV-reflecting layer adjacent the phosphor coating and/or dispersed in the phosphor coating so that the scattered UV rays are absorbed by the phosphor coating and cause the phosphor coating to emit visible light. The inorganic powder exhibits low or no absorption to UV rays having wavelengths of 185 nm and 254 nm and is not reactive with mercury.
