ABSTRACT:
A fluorescent device, such as a fluorescent light or a CRT, is formed with a fluorescent screen including an optically transparent supporting substrate and a fluorescent layer deposited on the substrate. The fluorescent layer contains a plurality of particles each quantum confined by a size, generally below 100 .ANG. dictated by a specific desired color of emitted light. Approximately 50 .ANG. provides yellow light with larger particles moving toward red and smaller particles moving toward blue. A source of fluorescent stimulation, generally including electron bombardment or ultraviolet light, is mounted in spaced relation to the screen.
