The voltage-tunable multicolor emission was realized in a poly(p-phenylene)/nanoporous ZnMnO organic-inorganic hybrid light-emitting diode. Red, green, and blue (RGB) colors sequentially appeared with increasing magnitude of the bias voltage (i.e., R → RG → RGB with V↑). At a higher voltage (>2.4 V), eventually, the device emitted the visible light with a mixture of colors including RGB. These unique features may move us a step closer to the application of organic-inorganic hybrid solid-state lighting devices for the full-color display and/or the electrical-to-optical data converter for multivalue electronic signal processes. In-depth analyses on electrical and optical properties are presented, and voltage-controllable multicolor-emission mechanisms are discussed.
在聚对苯撑（p-phenylene）/纳米多孔 ZnMnO 有机-无机杂化发光二极管中实现了电压可调的多色发射。随着偏置电压的增加（即 V↑），依次出现红色、绿色和蓝色（RGB）颜色。在更高的电压（>2.4 V）下，最终，该器件发出了包括 RGB 在内的混合颜色的可见光。这些独特的特征可能使我们更接近应用有机-无机杂化固态照明器件进行全彩色显示和/或用于多值电子信号处理的电-光数据转换器。本文介绍了对电和光性能的深入分析，并讨论了电压可控的多色发射机制。
