Controlled localized surface plasmon resonance wavelength for conductive nanoparticles over the ultraviolet to near-infrared region

摘要

We present several methods for tuning the localized surface plasmon resonance (LSPR) wavelength of conductive nanoparticles (NPs) over the ultraviolet to near-IR (UV-NIR) region. The methods presented in this article include changing the size of the icosahedral Pd NPs (LSPR in the UV region), using in-phase and antiphase surface plasmon coupling with octahedral Au NPs (LSPR in the visible region), and altering the carrier density in indium tin oxide NPs (LSPR in the NIR region) without changing the particle shape.
