| Abstract: | We report on the synthesis and optical spectra of silver nanorice particles. Two strong absorption bands are resolved in the near UV and near-IR region, and the dark field scattering spectra are consistent with the absorption spectra. Finite-difference time-domain simulations reveal that the peak in the IR region can be attributed to the E field that is parallel to the long axis, while the peak in the UV can be attributed to the E field perpendicular to the short axis of the silver nanorice particles. This paper reports on the synthesis of Ag nanorices, and their characterization by optical absorption, TEM, dark field scattering microscopy of single Ag nanorice and theoretical simulations using time domain finite-difference time-domain method. Electric field distribution of Ag nanorice dimer excited by polarization along long axis. |
