摘要
溶液法在柔性塑料衬底上制备轻薄的光电子器件具有低成本、大面积和易操作等显著优势。文章报道了一种基于AgNWs作阴极的全溶液法制备柔性量子点发光器件。引入PMMA介质层以降低氧化锌表面粗糙度, 平衡器件电荷注入, 提高器件性能。其器件的最大亮度为1 542 cd/m2, 电流效率达1.9 cd/A。在弯曲状态下, 发光均匀稳定, 呈半透明器件。
Abstract
Thin and light optoelectronic devices based on flexible plastic substrates by solution-processed fabrication have obvious advantages such as low cost, large area and easy operation. An all-solution flexible quantum dot light-emitting devices with silver nanowire cathode was presented. The introduction of PMMA dielectric layer could reduce the surface roughness of zinc oxide, balance device charge injection, and improve device performance. The device has the maximum brightness of 1 542 cd/m2 and the current efficiency of 1.9 cd/A. When the device bends, the light-emitting performance is uniform and stable, showing a semi-transparent state.
