Abstract
The earliest account of localized surface plasmon resonance (LSPR) has to date back to the ancient age of Rome in 400 A.D. The famous glass of Lycurgus cup told the story of unique light-and-matter interaction at the nanoscale that confines the electromagnetic field resonance at its surface and therefore allows LSPR feature to noticeably arise. The conventional metallic LSPR nanomaterials, like Au and Ag nanoparticles attract constant attentions due to their synthetic simplicity, chemical robustness, and visible spectral response. Its ability to generate sensitive dielectric sensing of the surroundings, strong electromagnetic field and active charge carriers upon optical excitation triggered widespread curiosities among researchers. However, there are growing interests for LSPR semiconductor nanomaterials as well. It is believed that LSPR of semiconductor nanomaterials exhibits a higher degree of tunability and broader range of spectral coverage deep into the infrared spectrum than LSPR of metallic nanomaterials. As a result, both of these metallic and semiconductor LSPRs have received relentless interests in the field of optics, biomedicines, catalysis, etc.
In this dissertation, I will focus my discussion on the synthetic challenge, material-specific plasmonic properties, and photocatalytic or photothermal behaviors of plasmonic metallic and semiconductor nanomaterials.
