Abstract
A mixed green-emitting phosphor manufactured by mixing about 20 to 60 weight percent of Y.sub.3 (Al,Ga).sub.5 O.sub.12 :Tb phosphor, less than about 30 weight percent of LaOCl:Tb phosphor, less than about 60 weight percent of Y.sub.2 SiO.sub.5 :Tb phosphor, and less than about 20 weight percent of Zn.sub.2 SiO.sub.4 :Mn phosphor and a cathode ray tube employing it are disclosed. The luminance characteristic is excellent under a high current density.
