[OLED4-4L] Directional and High Color Purity Laser-like Light from Organic Semiconductor Electroluminescent Device
Organic semiconductor, OLED, laser diode, light directionality control, high color purity
In this work we present an organic semiconductor electroluminescent device that produces light with high directionality (divergence angle of 3°) and high color purity (full width at half-maximum of 2 nm). These features were obtained by designing the electroluminescent device (including a gain emitting layer and distributed feedback resonator) so that the gain is increased by controlling the recombination zone. These are the first results in the ...
