— The subjects of this investigation are the transport of charge carriers and the spatial efficiency in thin‐film electroluminescent devices based on ZnS: Mn. Measurements with optional UV illumination were performed on a set of probe layer samples. The transfer of electrons and holes was studied and by comparing transient measurements with the steady‐state situation the creation of positive space charge during the first pulses is revealed and its location is estimated.
