State-of-the-art quantum nanomaterials synthesized in organic solvents fail to meet most requirements for aqueous and sustainable applications: they rely on toxic or volatile solvents, lose optical and electronic performance upon transfer to water, exhibit poor long-term stability under biologically relevant or ambient conditions, and are difficult to scale in an economical way.

To improve functional performance and accelerate real-world deployment, rational synthetic design, ligand and solvation engineering, and controlled interfacial chemistry are essential for high-brightness emitters, stable quantum light sources, biocompatible imaging probes, and sustainable optoelectronic devices.

My research aims to develop economically scalable design strategies covering green/benign solvent systems, ligand engineering and passivation approaches. Through systematic experimental characterization and theory-guided studies, solvation structure, ligand chemistry, and surface/interfacial layers will be revealed to determine optical–physical stability and mechanism. These efforts will be also complemented by AI-driven automated production and accelerated optimization in the near future, advancing the development of next-generation green, sustainable quantum nanomaterials.
