摘　　要：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 lightemitting 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 asprepared WLEDs, the corresponding color rendering index can reach up to 87 with a maximum luminance of262 cd/m2. This study may pave a new road to realize AIE-based WLEDs through a solution-processed technique.
