1. Aggregation-induced Emission (AIE) recommended by Prof. Ben Zhong Tang

AIE is a concept coined by Tang's group in 2001, introducing a type of luminescent materials that are contrary to Aggregation-caused quenching (ACQ) emitters. During the decades' development, the study and applications of AIE have been greatly expanded, including but not limited to bio-imaging, chemical sensors, devices, and many other aspects that are included in this collection.
