摘要： In the firing of a cerium-activated Y.sub.2 O.sub.3 -SiO.sub.2 system phosphor such as Y.sub.2 SiO.sub.5 :Ce and Y.sub.2 Si.sub.2 O.sub.7 :Ce, the improvement of adding BaF.sub.2 in a mol ratio of BaF.sub.2 /Y.sub.2 O.sub.3 of 0.01-0.1 is disclosed which increases the luminosity, emission intensity or both of the phosphor. Phosphors having improved properties are conveniently prepared according to the disclosed process.
