PRELIMINARY EXPERIMENTS ON ELECTROLUMINESCENCE OF ZINC SULFIDE

Abstract

A short review of the literature on electroluminescence (EL) is given. The analysis is limited to phosphors of (activated) ZnS type and to intrinsic EL, i.e., EL excited in condenser type cells, filled with powder phosphors embedded inA GOOD DIELECTRIC MEDIUM. A new technique, suggested for studying the behaviour of the EL, consists of applying to the cells single transients of voltage (respectively rising or falling) with a constant rate of variation vs time. The circuits used for this technique are described, as well as the preliminary results obtained with commercial EL cells. These results are of a good quantitative character.
