Action de la température sur l'électroluminescence de monocristaux de ZnS, de différentes compositions

Abstract
The electroluminescence of ZnS single crystals containing different amounts of copper is described. The electroluminescence is a maximum at a certain temperature characteristic of the crystal, this temperature being lower, the higher the copper concentration. These results are in accordance with a mechanism previously developed, if the effect of quenching of the light emission at high temperatures is considered.
