Abstract
White organic light-emitting devices (WOLEDs) with a novel direct hole-injection structure based on the hole transport capability of bis[2-(4-tert-butylphenyl) benzothiazolato-N,C2'] iridium(acetylacetonate) [(t-bt)2I-r(acac)] were fabricated. By inserting an electron-blocking layer, we successfully manipulated electron transport and achieved white light emission. A maximum luminance of 26020 cd/m2, a maximum current efficiency of 22.37 cd/A and a maximum power efficiency of 18.99 lm/W were obtained. This novel structure can significantly simplify the production processes of WOLEDs and deserves further investigation.
