The formation and relaxation of plasmon-induced hot electrons in Au nanodisks (AuNDs) with relatively large particle size was studied by femtosecond pump-probe spectroscopy. We temporally resolved the plasmon-induced formation of nonthermal electrons

We report excitation light-induced anisotropies in polarized SHG for Au nanoprisms at LSP resonances. The anisotropies were more pronounced in higher excitation powers. The phenomena were explained by taking account of 2nd and 4th-order nonlinearitie

The paper presents second harmonic generations (SHG) from Au nanoprisms at localized surface plasmon resonances. The model system was equilateral triangular nanoprisms that were arranged two-dimensionally in trigonal lattices. At lower excitation pow

Polarized SHG spectroscopies were performed for three-fold rotationally symmetric Au trianglur nanoprisms. The LSP-enhanced SHG radiations arose from excitations due to not only the near-fields oscillating within the triangular surface but those perp

Polarized second-harmonic-generation (SHG) spectroscopy was studied for Au nanorods arrayed on fused silica substrates at localized surface plasmon (LSP) resonances. The geometry of the nanorods is centrosymmetric and electric dipolar second-order no
