Mainly engaged in surface enhanced Raman scattering and spectroelectrochemistry research. Surface enhanced Raman scattering (SERS) spectra of various pure transition metal systems were obtained, which confirmed that transition metals of VIII B group had weak SERS effect, and were applied to electrocatalysis research of fuel cells and corrosion protection of stainless steel. A new potential average Raman spectroscopy method is established by using time-resolved Raman spectroscopy technology which is not limited by the resolution of spectrometer detector. The technology of electrochemical construction of electrode nanometer spacing on microchip has also been developed. Specially shaped nanoparticles were designed and synthesized, and their characteristics including plasma vibration absorption were characterized.

Mainly engaged in photochromic research of organic nano-systems and composite films. The regulation of photochemical and photophysical properties in organic nano-systems is realized, and the research on the specificity of nano-materials is extended to the field of organic small molecules. Nano-spheres, nano-blocks, nanowires, nanotubes and other organic light functional nanostructures were prepared, and their morphology was regulated and protected. It is found that with the increase of particle size, the confinement effect of intermolecular charge transfer excitons gradually moves to the low energy end. By controlling the particle size, the emission wavelength of pyrazoline derivative DAP nanostructure materials can be controlled. Nanoscale photochromic ultrathin films were constructed by using supramolecular chemistry concept and molecular assembly technology. By compounding with precious metals, the photochromic efficiency of transition metal oxide films is improved by 5 times. The amplification principle of semiconductor and noble metal schottky junction is put forward. A single-layer photochromic ultrathin film with a thickness less than 2nm was also prepared.
