研究领域

1. Hybrid organic-inorgnic solide-state materials: synthesis, characterization, and devices. Hybrid organic-inorgnic materials combine both molecular tunability from the organic phase, and the photophysical properties from the inorganic sublattice, thus offer a rich playground for chemist to design new materials with exotic, yet tunable, optical, electronic, and magnetic properties. We are particularly interested in developing solution-processable hybrid organic-inorganic semiconductors for cheap, efficient, and flexible optoelectronics including solar cell, photodetector, LED, and spin-optoelectronics. We explore the concept of symmetry-breaking enabled by chemical tools to afford non-centrosymmetric materials, such as, chiral hybrid metal-halide semiconductors, to twist photons via light-matter interaction, and to align electron spin states via the chiral induced spin selectivity (CISS). We fabricate next-generation spin-optoelectronic devices such as spin-LEDs that can control charge, spin and light with symmetry-breaking semiconductors. We seek to understand how the breaking of spatial reversal symmetry induces unconventional phenomenon coupled with light, charge and spin. 2. Colloidal semiconductor nanocrystals: synthesis, photophysics and photochemistry. Collidal semiconductor nanocrystals are a class of nanocrystalline materials that exhibit very interesting photophysical properties due to quantum confinement. For instance, due to the quantized energy and relaxation of the translational momentum conservation rule, "Auger process" can be much more efficient than bulk semiconductors, generating high energy hot electrons. Our group is particularly interested in understanding their rich photophysics with spectroscopic tools, and to unitilize their unique photophysical properties to enable challenging photonic process and chemical transformations. We are interested in developing a nanocrystal-based composite that can efficiently convert NIR photons to visible photons via a photon upconversion process. We are also exploring new photophysical processes such as Auger process, thermally activated delayed fluorescence (TADF), localize surface plasmonic resonance (LSPR), and spin-involved photochemistry to enable challenging two-photon process and chemical transformations.
