Ambipolar organic phototransistors were fabricated using a natural pigment 6,6'-dibromoindigo (6-BrIG) as the active channel. These phototransistors yielded significantly enhanced currents upon light illumination with photoresponsivities and external quantum efficiencies as high as 10.3 A W and 2437% for the n-channel, and 55.4 mA W and 13.1% for the p-channel, respectively. In addition, simple inverter complementary circuits were fabricated by integrating two ambipolar phototransistors. Channel current was dependent on light intensity and voltage bias. This study provides a basis for an in-depth understanding of the optoelectronic characteristics of 6-BrIG, and introduces this material as an ecofriendly candidate for optoelectronic applications.
采用天然色素6,6'-二溴靛蓝（6-BrIG）作为有源沟道制备了双极性有机光电晶体管。这些光电晶体管在光照下产生了显著增强的电流，n沟道的光响应度和外量子效率分别高达10.3 A/W和2437%，p沟道的分别为55.4 mA/W和13.1%。此外，通过集成两个双极性光电晶体管制作了简单的反相器互补电路。沟道电流取决于光强和电压偏置。该研究为深入了解6-BrIG的光电特性提供了基础，并将这种材料作为一种环保的光电应用候选材料引入。
