摘要

This study presents the influences of dye doping and hole blocking layer insertion on the electroluminescent properties of the blue organic light emitting diode. The luminance of the device was significantly improved by BCzVB doping because of the utilization of effective Förster energy transfer and the improvement of carrier injection and trapping; a BCzVB dominant emission was observed. Furthermore, when a BCP layer was inserted between the TBADN:BCzVB and Alq3 layers, a thin BCP layer insertion enhanced the injection of electrons and improved the luminance of the device. In contrast, a thick BCP layer insertion caused a delay in electron transport, resulting in a decrease in current density and a deterioration in luminance.
