Low-Voltage Cathodoluminescent Phosphors

Abstract

Phosphors have been used for the display of information since the invention of the cathode-ray tube (CRT) by Karl Ferdinand Braun in 1897. With the development of color television, an effort spanning approximately 30 years, came the most significant advances in phosphor technology. The most noteworthy was the shift to the all-sulfide system, and discovery of the red, rare-earth oxysulfide phosphors.
