Innovation of Spectroscopic Techniques
Research Interests
Polarized Resonance
Synchronous Spectroscopy
(PRS2)
Our group has developed multiple innovative spectroscopic techniques including PRS2 and PAOS, which can quantify 7 new optical parameters that allow us to understand new insights of advanced optical materials and molecular assembly process. This is the main research area in our lab.
Interfacial
Interactions
We are interested in the ligand adsorption and desorption and displacement, and reaction on the plasmonic gold nanoparticle and silver nanoparticles. The model ligands include proteins, DNA, and small molecules such as electrolytes, organothiols, thioamides, and other organic species.
ABOUT US
We are analytical or physical chemists who utilize light for material characterizations. Light/matter interactions are likely the most studied topic in science and the phenomena from light/matter interactions are used extensively for a wide range of material characterizations. Unfortunately, existing photon absorption, scattering, and fluorescence measurements often ignores the complex interplay of the photon absorption, scattering, and on-resonance emission that can concurrently occur in many realistic samples. Our group has recently invented a new spectroscopic method termed as “Polarized resonance synchronous spectroscopy (PRS2)”. When used in combination with conventional UV-vis and fluorescence measurements, this PRS2 spectroscopic technique has enables for the first time the quantitative decoupling of the interplay of the material photon absorption, scattering, and on-resonance fluorescence emission. Current research in our group is on the PRS2 applications in material characterizations.
