摘要

A green emitting phosphor for heavily loaded cathode-ray tubes comprises a mixture of a deep-green and a yellowish-green emitting phosphor. Mixtures of Zn2SiO4:Mn and at least one phosphor from the group comprising Y2SiO5:Tb; X2O2S:Tb; ES:Ce and XOZ:Tb, where X=Y, La, Gd, Lu; E=Ca, Sr, Ba; and Z=Cl, Br, I, F; satisfy, as FIG. 1 illustrates for a few examples, the EBU specification.
