A phosphor comprises a borate of terbium, at least an alkaline-earth metal, and at least a Group-3 metal. In one embodiment, the phosphor has a formula of A<SUB>3</SUB>(D<SUB>1-x</SUB>Tb<SUB>x</SUB>)<SUB>3</SUB>(BO<SUB>3</SUB>)<SUB>5</SUB>; wherein A is at least an alkaline-earth metal selected from the group consisting of calcium, barium, strontium, and magnesium; D is at least a Group-3 metal selected from the group consisting of lanthanum, scandium, and yttrium; and 0<x<0.5. The phosphor can be used in light sources such as those based on mercury discharge or light-emitting diodes and in displays.
