Description:: In this work, computational electrodynamics is used to calculate extinction, scattering, and local electric fields around the transition metal nanoparticles. Rhodium and ruthenium exhibit plasmon peak shifts as a function of local refractive index comparable to particles of silver and gold.1,2 In addition, the local fields calculated indicate that Rh...

Description:: In this experiment, the optical properties of several spherical nanoparticles were observed. Particles were modeled using Mie theory, a set of equations that calculate the extinction coefficient of virtually any spherical particle. Initially this theory was used to model solid particles made of noble metals. As time passed, its scope...

Description:: The optical properties of spherical gold nanoparticles are calculated using classical electrodynamics. The wavelength corresponding to maximum extinction shifts to longer wavelengths as the size of the nanoparticle is increased. The influence of higher-order multipoles is evident for large nanoparticles, making the spectra more complex. When the shell thickness of...

Description:: Chemists and physicists have been interested in the optical properties of metal nanoparticles since the time of Michael Faraday.1 New approximation techniques for different sizes and geometries have created renewed interest in and investigation of these particles. Many different arrays of particle extinctions of various shapes and sizes have been...
