Optical Spectroscopy
Polarized Resonance Synchronous Spectroscopy
(PRS2)
PRS2 is capable of decomposition of UV-vis into absorption and scattering component spectra, which has been demonstrated its applications in several areas, including gold nanoparticles, molecular assembly and disassembly, fluorescent quantum dots and aggregation induced emission.
Anti-Stokes-shifted, on-resonance, and Stokes-shifted Spectroscopy (PAOS)
PAOS is a self-contained method that allows direct separation and quantification of the scattering and on-resonance-fluorescence (ORF) cross-sections and their depolarizations. It is particularly handy for optical complicated materials with non-zero scattering depolarization and detectable ORF.
Inner-Filter-Effect (IFE) Correction
Sample self-absorption, or inner-filter-effect (IFE), attenuates the spectral intensities because it absorb the excitation photons and emission photons. Our group developed a technique to determine the effective path lengths that enable precise IFE correction, which is critical for characterization of material scattering and fluorescence activities.
