| Research Abstract |
We have succeeded to tune the localized surface plasmon resonance (LSPR) wavelength of conductive nanoparticles (NPs) over the ultraviolet to near-IR (UV-NIR) region. The methods include the changing the size of the icosahedral Pd NPs (LSPR in the UV-NIR 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. We have also demonstrated the electron transfer from Au NPs to the conduction band of semiconductor NPs using Au/semiconductor (ZnS, CdS, CdSe) heterostructured NPs.
