Abstract

Optical radiation efficiency is the ratio of scattering cross section to extinction cross section. Optical radiation efficiency has been calculated, using classical electrostatics, for spherical nanoparticles of Ag, Au, Cu, Co, Cr, Ni, Pd, Pt, Sn, and Ti. The particle diameter was varied and calculated for the wavelengths in the range of 400-1200nm. The change in radiation efficiency in glass medium with respect to the size of the particle has been observed. The validation of calculation is confirmed by finding and comparing the efficiencies for Ag, Au, Cu in Dhumale 2012. This work has considered all the materials considered by Tanabe 2007.
