Some Studies on a PC-EL Type Solid-State Image Intensifier (Invited Paper)

Abstract

A solid-state image intensifier consists basically of a photoconducting layer (PC) and an electroluminescent layer (EL) sandwiched together between two transparent conducting electrodes. When an ac field is applied to this sandwich, it is possible to obtain on the output EL layer, an intensified version of the optical image presented on the input PC surface. Several sandwich type solid-state image intensifiers (SSII) have been fabricated in our laboratory. The fabrication and characterisation of a PC-EL panel consisting of CdSSe(Cu) powder in polystyrene binder as PC layer and ZnS(Cu) in cynoethyl cellulose binder as EL layer are reported here.
