摘要 基于空穴阻挡层BCP掺杂红光染料DCJTB的简单体系制备了一种电压调制发光颜色的有机电致发光二极管(OLED)。器件发光颜色随电压改变发生了从橙色到紫色的连续变化。通过不同层间的能级势垒对这种发光颜色改变的特性进行了合理化的解释。 Demonstrate a simple model for the voltage-induced alteration of emission color from the organic light emitting diodes (OLED) based on 4-(dicyanomethylene)-2-t-butyl-6-(1,1,7,7-tetramethyljulolidyl-9-enyl)-4H-pyran (DCJTB) doped into 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline(BCP).The device displays a continuous change of color from orange to purple depending on the applied bias. The emitting characteristics can be rationalized by the potential energy barriers at the interface between different layers.
