Abstract

Highly luminescent network films on flat indium tin oxide (ITO) substrates are prepared by electropolymerization using an electroactive and fluorescent compound as precursor; the LEDs prepared using these films as a light emitting layer achieve the maximum luminance and external quantum efficiency of 4224 cd/m(2) and 0.72%, respectively, which demonstrates that electrochemical synthesis can be a new route to construct the highly luminescent films.

摘要

通过电聚合，以一种电活性荧光化合物为前驱体，在平坦的铟锡氧化物（ITO）衬底上制备出高发光网络薄膜；使用这些薄膜作为发光层制备的发光二极管分别实现了4224 cd/m²的最大亮度和0.72%的外量子效率，这表明电化学合成可以成为构建高发光薄膜的一条新途径。
