Highly efficient p-i-n-type organic light emitting diodes on ZnO:Al substrates

Abstract: Aluminum doped zinc oxide (ZAO) is presented in this letter as an alternative transparent electrode: optimized ZAO films offer excellent parameters for organic light emitting diodes (OLEDs). The ZAO films are applied to various p-i-n-type OLEDs. By using green phosphorescent molecules in a double emitter structure, very high efficiencies were obtained, namely, 54.6 cd/A and 61.5 lm/W for 100 cd/m(2) at 2.78 V. Additionally, white OLEDs on ZAO demonstrated pure white emission independent of the luminance and hi… Show more

“…Transparent conducting oxide (TCO) thin films are widely used as transparent electrodes in a variety of optoelectronic devices, such as liquid crystal displays,1 solar cell panels,2 and organic light emitting displays 3, 4. As the most commonly used TCO material, indium tin oxide (ITO) shows high conductivity and optical transparency over visible wavelengths.…”

“…Subsequently, WOLEDs were produced by vacuum deposition of a blend of three kinds of phosphorescent emitters [32]. WOLEDs with a multilayer device structure have also been fabricated [33,34]. In this device structure, excitons can be generated in an EML by direct recombination of holes and electrons or by energy transfer from a neighboring EML.…”
