溶液工艺是制造大面积、低成本半导体器件的关键技术，因此受到学术界和工业界的广泛关注。在这里，我们首次实现了溶液处理的发光二极管(不包括阴极)，基于聚集态诱导发射(AIE)分子的四苯基乙烯-4CL(TPE-4CL)和无镉半导体纳米晶(NCS)。采用溶液法制备了一种新型的环保型白光发光二极管(WLED)，将CuIn-Zn-S纳米CS与TPE-4CL混合作为发光层。对所制备的WLED进行系统优化后，对应的显色指数可达87，最大亮度可达。262.。Cd/。M.2.这项研究可能为通过溶液处理技术实现基于AIE的WLED铺平新的道路。
Solution process is a key technique for the manufacture of large-area and low-cost semiconducting devices and, thus, attracts a lot of attention from both academia and industry. Herein, we realized solution-processed light-emitting diodes (excluding a cathode) based on aggregation-induced emission (AIE) molecules of tetraphenylethylene-4Cl (TPE-4Cl) and cadimum-free semiconductor nanocrystals (NCs) for the first time. By mixing Cu-In-Zn-S NCs and TPE-4Cl as an emissive layer, a new type of environmentally friendly white-light-emitting diodes (WLEDs) was prepared through a solution-processed technique. After systematical optimization of the as-prepared WLEDs, the corresponding color rendering index can reach up to 87 with a maximum luminance of . 262. . cd/. m. 2. . This study may pave a new road to realize AIE-based WLEDs through a solution-processed technique.
