Cooperative MXene transparent electrode-based efficient microcavity organic light-emitting diode and preparation method thereof

Abstract

The invention discloses an efficient microcavity organic light-emitting diode based on a collaborative MXene transparent electrode and a preparation method thereof, and belongs to a light-emitting diode. A dielectric medium-MXene-dielectric medium (DMD) synergistic electrode is prepared, a Fabry-Port microcavity resonance effect is utilized, the thickness of each film layer of the organic light-emitting diode is adjusted, cavity mode distribution is accurately adjusted and controlled, the formant position is adjusted and controlled to a light-emitting layer, and secondary utilization of an internal light field of the device is achieved. Finally, a transparent conductive electrode with high transmittance, high conductivity and low haze is realized, and a blue light OLED device with high external quantum efficiency, excellent brightness and excellent efficiency roll-off characteristics is prepared.
