Printed organometal halide perovskite light-emitting diodes (LEDs) are reported that have indium tin oxide (ITO) or carbon nanotubes (CNTs) as the transparent anode, a printed composite film consisting of methylammonium lead tribromide (Br-Pero) and poly(ethylene oxide) (PEO) as the emissive layer, and printed silver nanowires as the cathode. The fabrication can be carried out in ambient air without humidity control. The devices on ITO/glass have a low turn-on voltage of 2.6 V, a maximum luminance intensity of 21014 cd m(-2), and a maximum external quantum efficiency (EQE) of 1.1%, surpassing previous reported perovskite LEDs. The devices on CNTs/polymer were able to be strained to 5 mm radius of curvature without affecting device properties.
已报道打印的有机金属卤化物钙钛矿发光二极管（LED），其透明阳极为氧化铟锡（ITO）或碳纳米管（CNTs），发射层为打印的由溴化甲脒铅（Br-Pero）和聚氧化乙烯（PEO）组成的复合薄膜，以及打印的银纳米线作为阴极。制造可以在没有湿度控制的环境空气中进行。ITO/玻璃上的器件具有低的开启电压 2.6V，最大亮度强度 21014 cd m(-2)，最大外量子效率（EQE）为 1.1%，超过了先前报道的钙钛矿 LED。在 CNTs/聚合物上的器件可以被拉伸至 5mm 的曲率半径而不影响器件性能。
