ABSTRACT:
Apparatus for generating ultraviolet light of high intensity without production of heat, including an anode cathodoluminescent layer composed of a phosphor luminescent in the ultraviolet spectrum, a cold cathode electron emitting layer separated by an evacuated region from the cathodoluminescent layer, and a direct current electric field generated between cathode and anode across the evacuated region.
