FIELD: electroluminescent devices.
SUBSTANCE: proposed electroluminescent device has substrate, at least two electrodes disposed on mentioned substrate, at least three-dimensional percolation layer of metal mesa-porous structure disposed on this substrate between mentioned electrodes, this structure controlling plurality of cavities of micrometric and nanometric size. Cavities of three-dimensional percolation layer hold plurality of luminescent inclusions emitting light beams when they are excited by electrons passed due to tunneling effect through mentioned three-dimensional percolation layer. Electroluminescent devices of such design are competitive with commonly used ones, such as light-emitting diodes and optocouplers.
EFFECT: reduced cost, enhanced performance characteristics.
