Description

A remarkably improved high brightness phosphor, Y/sub 3/Al/sub 5-x/Ga/sub x/O/sub 12/:Tb (x = 0 -- 5) was developed and has been adopted for the projection CRT. The replacement of a portion of Al with Ga in YAG improved the brightness and the saturation characteristics. While the brightness of Y/sub 3/Al/sub 3/Ga/sub 2/O/sub 12/:Tb is almost the same as that of Y/sub 3/Al/sub 5/O/sub 12/:Tb at low cathode current densities, the former becomes about two times greater than the latter at high cathode current densities. The brightness of the Y/sub 3/Al/sub 5-x/Ga/sub x/O/sub 12/:Tb phosphor and its saturation characteristics are presented and compared with other green phosphors which have been used for the projection CRT
