Abstract
WORK on electroluminescence at the AEI Central Research Laboratory has been aimed at producing layers for a solid-state image intensifier. These usually consist of a combination of an a.c. electroluminescent layer with a photoconducting layer. To avoid the problems associated with capacitive coupling we have concentrated our attention on electroluminescent layers which operate under d.c. conditions. Initial investigations were directed at the production of thin films showing good d.c. electroluminescence ; the results of these investigations have been reported elsewhere1–3, but subsequent investigation has shown that brighter and more efficient cells could be prepared using powder phosphors.
