Mixed phosphor emitting a green light, and cathode ray tube employing it

摘要

A mixed phosphor emitting a green light, which is prepared by mixing from 20 to 60 % by weight of Y3(Al,Ga)5O12: Tb phosphor, less than 30 % by weight of LaOCl: Tb phosphor, less than 60 % by weight of Y2SiO5: Tb phosphur and less than 20 % by weight of Zn2SiO: Mn phosphur, and a cathode ray tube employing said phosphur are described. The luminance properties are excellent at high current density.
