摘要
采用HAT-CN/CuPc 作为有机电致发光二极管(OLED)蓝光ADN 器件的组合空穴注入层(HIL)。通过采用该组合HIL 后，在保证器件电流效率不下降的情况下有效地降低器件的驱动电压。一方面，这是利用HAT-CN 可以大幅提高CuPc 薄膜的有序度，有效地降低CuPc HIL 的电阻；另一方面是因为HAT-CN/CuPc 可以实现空穴的有效注入。这两方面因素最终使得ADN 蓝光器件的启亮电压降低至3.4 V，较采用CuPc HIL 的ADN 蓝光器件低0.5 V。
Abstract
HAT-CN/CuPc is adopted as hole injection layer (HIL) in organic light-emitting diodes (OLEDs). While this combination is inserted in the ADN blue device, the driven voltage is lower down efficitively without losing the current efficiency. This result is caused by two reasons. The one is the improved crystallinity of CuPc film that is induced by the HAT-CN thin film, which can decrease the electric resistance of HIL effectively. And the other one is the efficacious hole injection efficiency that is achieved by HAT-CN/CuPc. The turn-on voltage of HAT-CN/CuPc device can reduce to 3.4 V, which is 0.5 V lower than that with CuPc as HIL.
