详细
Particle shape effects in the absorption and scattering spectra of gold and silver nanoparticles are studied for optical-range radiation. Numerical calculations of extinction cross section are performed using the FDTD approach for particles of three shapes: disks, triangular prisms, and triradial-base prisms. It is established that the spectra of nanoparticles of different shapes differ qualitatively even if they are of the same characteristic dimensions. The obtained results can be used to develop a spectroscopic procedure for determining the shape of metallic nanoparticles and producing quantitative estimates of their characteristic dimensions.
