Popis: | We report efficient transparent small-molecule organic light-emitting devices (OLEDs) with laminated top transparent electrode. This was made possible via the aid of the transparent conductive adhesive based on conducting polymers. With use of small-molecule materials and efficient phosphorescent emitters, rather high external quantum efficiency and current efficiency of up to (11.4%, 43.1 cd/A), much higher than those in previously reported OLEDs using laminated top electrodes, were obtained. The transparent OLEDs exhibited rather balanced electroluminescent intensities and spectra from both sides of the devices, a broad optical transmission band, and a high optical transmittance of up to 77%. It provides a simple and yet effective approach for fabrication of efficient transparent OLEDs and can be extended to flexible devices or even roll-to-roll processes in future. |
