Abstract
The brightness of small size terbium activated gadolinium oxysulfide (Gd.sub.2-x Tb.sub.x O.sub.2 S) phosphor is increased by the incorporation of a lithium dopant. The lithium dopant is added to the phosphor by mixing lithium phosphate with the raw materials formulated to make the phosphor.
