Plasmonics has proven applications in improving photocatalysis, photothermal and photovoltaic cells. There are some issues with optimizing energy transfer and the decay of the plasmon oscillation in conjunction with semiconductors. Direct charge transfer results in chemical interface damping of plasmon and occurs during the plasmon lifetime. In the case of sequential charge transfer the plasmon has already decayed into energetic electrons and holes. The focus of our research is to explore the material properties of plasmonic gold nanorods such as aspect ratio and plasmon wavelength and semiconductor Schottky barriers. We are using dark-field spectroscopy and photoluminesce spectroscopy to acquire line spectra data, and optimize the energy output of the plasmon and quantify charge transfer from the direct charge transfer mechanism versus sequential charge transfer mechanism.
