[Also in Division H1] A electroluminescent panel consists of a monolayer of semi-conductor grains between two electrodes and held together by an insulating binder, at least one of the electrodes being radiation transmissive, and there being at least two types (e.g. three types) of grain in the layer which may provide light of predetermined colours. The grains may contain PN junctions. Contact resistance and radiation absorption is reduced by the provision of mono-grain layers. Individual grains used may not be uniformly doped-they may be doped differently across the thickness of the layer or the doping of the surface of the grains may differ from that of the cores.
