Cathode-ray-tube phosphors: Principles and applications

Abstract

Principles and applications of phosphors in cathode-ray tubes are discussed. Among the basic parameters covered are: back-scattering, secondary emission, penetration, electronic transitions, dead voltage and energy, and optical efficiencies. Various relevant aspects of television kinescopes are discussed, including commercially used phosphor characteristics and screening techniques, radar tubes, image tubes, voltage-dependent color displays, flying-spot and beam-indexing tubes, projection, printing, and infrared stimulation systems. Colorimetry and photometry, as applied to phosphors, are discussed, including the CIE and UCS systems.
