An optoelectronic memory element was constructed from two photoconducting (PC) and two electroluminescent (EL) devices. Between one EL device and one PC device an optical feedback was provided, so that these two components constituted a bi-stable system. Experimental details of preparation of the PC-EL type thin film systems and results of investigations of the memory element are presented.
