Abstract: The sensitivity of YPO4:Ce phosphors to 185 nm radiation may be increased by incorporating a praseodymium coactivator. The use of Ce and Pr as co-activators in a YPO4 phosphor improves the sensitivity of the phosphor to excitation by both 185 nm and 254 nm radiation and should increase total UVA and UVB output in fluorescent lamps. The co-activated phosphor has emission peaks at about 355 nm and about 335 nm.

Abstract: A Sr(Al,Mg)12O19:Ce,Pr phosphor is described wherein the phosphor has an increased sensitivity to excitation by 185 nm radiation compared to a Sr(Al,Mg)12O19:Ce phosphor. The Ce,Pr-coativated strontium magnesium aluminate phosphor emits ultraviolet (UV) radiation at about 306 nm in the UVB region. Suntan lamps made with this phosphor exhibit improved performance over lamps made with a commercial Sr(Al,Mg)12O19:Ce phosphor.

The holdover stability of the treated SrB4O7:Eu phosphor improves the 100-hour maintenance in a fluorescent tanning lamp to the extent that the treated phosphor may be subject to a holdover period of more than 25 days without a significant change in its 100-hour maintenance.

Abstract: A method is provided for making narrow-band, UVB-emitting, (Y,Gd,Ce,Pr)Mg borate phosphors. The method involves the use of a mixed oxide co-precipitate which is combined with MgO and boric acid and fired twice to form the borate phosphor. The mixed oxide co-precipitate is formed by dissolving sources of Y, Gd, Ce, and optionally Pr, in an acid solution. Oxalic acid or ammonia is added to the solution (or vice versa) to form a co-precipitate of oxalates or hydroxides that are further fired to obtain a mixed oxide co-precipitate. The use of the mixed oxide co-precipitate improves homogeneity and yields a phosphor having a higher brightness with very little or no sticking between the fired cakes and the firing crucibles.
