摘要： The present invention is directed to phosphors exhibiting efficient, narrow band UV emission, with peak emission at 330 nm (from excitation at 254). These phosphors are cerium-activated calcium pyrophosphate (beta-phase) of nominal formulationCa(.sub.2-w-x-y) (NSF).sub.w Ce.sub.x Na.sub.y P.sub.2 O.sub.7wherein:NSF is the non-stoicheometric factor;0.ltoreq.w.ltoreq.0.1;0.05.ltoreq.x.ltoreq.0.20; and0.05.ltoreq.y.ltoreq.0.20.
