Abstract

A broadband cathodoluminescent phosphor having applications in CRT displays has been found. The phosphor essentially emits 'white light' and can be filtered to give various color emissions. The emission intensity of this phosphor is comparable to the efficient commercial P1 (Zn(2)SiO(4):Mn) phosphor, which has the best efficiency among commercially available phosphors. Because of its broadband emission, the luminous efficiency of this phosphor is much higher than that of P1 (40 lumen/ watts).
