Research

We are interested in developing luminescent nanomaterials especially fluorescent materials for various applications in sensing, imaging, and lighting. We also utilize the single-molecule spectroscopy to characterize the heterogeneous nano-catalysts. Properties in both ensemble and single-molecule levels are investigated.

Carbon dots with full color fluorescence

We develop carbon dots with full visible emissions, study their properties in both ensemble and single-molecule levels, and use them for chemical sensing and bio-imaging.

White fluorescence nanomaterials and the CIE diagram

We apply luminescent nanoparticles for organic light-emitting diodes. Nanoparticles’ properties in fluorescence, phosphorescence, and thermally activated delayed fluorescence are investigated and utilized.

Illustration of TIRF microscopy for single-molecule catalysis

We use single-molecule fluorescence spectroscopy to characterize heterogeneous nano-catalysts. We design and develop novel fluorogenic reactions and investigate the reaction mechanisms at the single-molecule level. We are interested in the reaction pathways, hidden intermediates, and heterogeneity and dynamic properties of catalysis. With this, we expect to better understand catalytic mechanisms and develop efficient catalytic systems.
