Abstract

Cathodochromic materials undergo a color change upon excitation by an electron beam, but can be restored to their original color by light irradiation. These materials have been incorporated into cathode-ray tubes, in place of the normal phosphor, to form light erasable dark trace storage tubes having high resolution capabilities.
