ABSTRACT:
The present invention is a single-component, UV-emitting phosphor having a composition represented by the general formula (Y1−x−y−zLaxGdyCeZ)PO4where x has a value in a range from 0.001 to 0.98, y has a value in a range from 0 and 0.1, z has a value in a range from 0.01 and 0.2, and x+y+z<1. The phosphor when stimulated by 254 nm radiation emits in both the UVA and UVB regions. The relative balance of the UVA and UVB emissions may be varied by adjusting the relative amounts of Y and La. Brightness can be increased by adding Gd to the composition.
