| Outline of Final Research Achievements |
Localized surface plasmon resonance (LSPR) is a collective oscillation of conduction electrons that have been directly excited by light, and it is a characteristic optical response of metal nanoparticles. LSPRs provide an electric field enhancement nearby the nanoparticle’s surface. Such a strong near-field can dramatically improve the efficiency of light-matter interaction and enables various photonic applications. In this project, frequency-tunable LSPRs of doped semiconductor nanoparticles were studied. Fundamental optical properties of copper sulfide nanoparticles were investigated and characteristics of their LSPRs were elucidated. Furthermore, fabrication methods of frequency-tunable plasmonic copper sulfide nanoparticles were developed.
