Bright Green Phosphor, Y 3Al5 − x Ga x O 12 : Tb , for Projection CRT
K. Ohno, Toru Abe · Journal of The Electrochemical Society · 1987
A remarkably improved high brightness phosphor, 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 is almost the same as that of at low cathode current densities, the former becomes about two times greater than the latter at high cathode current densities. The brightness of the phosphor and its saturation characteristics are presented and compared with other green phosphors which have been used for the projection CRT.
