Excitation of Electroluminescence by a Rotating Electric Field

Abstract

The principle of operation of an electroluminescence capacitor (ELC) in which a powder zinc sulfide electroluminophor is excited by three‐phase voltage is described. Rotation of the electric field intensity vector in a luminophor‐dielectric layer allows a substantially greater number of energy barriers to be involved in the collision processes in the luminophor grains than in a conventional ELC. This provides the possibility of retarding the ELC degradation: at the same initial brightness the time of its half‐decay increases several times.
