Abstract
In order to understand surface plasmon resonance of anisotropic metal nanocrystals, we have produced Ag nanorods with well-controlled aspect ratio by soft template method with seed-mediated. The aspect ratio of synthesized Ag nanorods can be tuned flexibly by changing the amounts of seeds. This provides a convenience for studying localized surface plasmon resonance (LSPR) properties of Ag nanorods. Based on these excellent properties, we calculated the extinction spectrum and electrical field distribution of Ag nanorods near the AgNCs by discrete dipole approximation (DDA) method and investigated the effect of incident and polarization direction on far-field and near-field characteristics. These results could be helpful for us to take the advantage of excellent optical properties on optoelectronic and biomedical field.
