    摘要： There is provided organic light emitting diode (OLED) device that include an organic electroluminescent layer formed between a first electrode and a second electrode. The organic electroluminescent layer is formed of a photo-crosslinkable liquid having dichroic molecules therein, and has a grating pattern defined therein by exposure of regions of the organic electroluminescent layer to a light beam. The refractive index of the exposed regions of the organic electroluminescent layer varies across the grating pattern. A method for fabricating the OLED device is also provided that includes providing the organic electroluminescent layer and defining the grating pattern in the photo-crosslinkable liquid by illuminating regions of the organic electroluminescent layer with a light beam. The refractive index of the defined grating pattern is tuned by adjusting the dosage of light to which the photo-crosslinkable liquid is exposed.

    摘要： An organic light emitting diode (OLED) having an organic electroluminescent layer formed between a first electrode and a second electrode. One of the first and second electrodes is a transparent electrode having a surface through which light is emitted from the OLED to the outside. The transparent electrode has a plasmonic photonic crystal structure fabricated having an artificial lattice with a pitch in density variation intermediate in size between a metallic crystal and a photonic crystal formed in the same material as the transparent electrode, thereby operable to suppress propagation of the surface plasmon polaritons at the surface.
