Abstract

A mixed green-emitting phosphorus manufactured by mixing InBO.sub.3 :Tb and one selected from ZnS:Cu,Au,Al and ZnS:Cu,Al, optionally with Zn.sub.2 SiO.sub.4 :Mn. A cathode ray tube adopting the mixed green-emitting phosphor not only has good luminance and color purity, but also enhanced afterglow and luminosity characteristics.
