Abstract
A light emitting diode of the stacked-layer structure type, incorporating at least one layer made of an inorganic material between the layer forming the substrate and a layer forming the light emitting layer, is provided, in which a periodic structure at the wavelength range emitted by the light emitting layer is printed.
Also described is a method for generating a microstructure periodic with a wavelength range of the emitting layer of a light emitting diode. The method includes: depositing an inorganic material layer by a sol-gel process between the substrate and a light emitting layer, and printing the periodic structure onto the outer surface of this layer by soft lithography, as well as using this process for manufacturing a light emitting diode.
