A uranium-based phosphor selected from (i) phosphors having formula I or II:

##STR00001##

where the phosphor having formula I or II is doped with an activator ion including Pr.sup.3+, Sm.sup.3+, or mixtures thereof, where 0a1, 0b1, 0.75x1.25, 0.75y1.25, 0.75z1.25, 2.5p3.5, 1.75q2.25, and 3.5r4.5; (ii) a phosphor having formula I or II, where the phosphor having formula I or II is doped with an activator ion selected from Eu.sup.3+, Pr.sup.3+, Sm.sup.3+, and mixtures thereof; and a counter ion comprising one or more alkali metal ions; and (iii) phosphors having formula III

##STR00002##

where the phosphors having formula III are doped with an activator ion selected from: Eu.sup.3+, Pr.sup.3+, Sm.sup.3+, and mixtures thereof, where A is Li, Na, K, Rb, Cs, or a combination thereof.
