Electronic temperature effects on the optical response of metal nanoparticles - art. no. 63432S

At the present work we study the optical properties of spherical nanometals by Lindhard's quantum theory for the electron gas and then there is a theoretical study aiming at understanding the role of the electronic temperature on the optical response of simple metal clusters as the nanoparticles. The electronic temperature dependence of the optical response of simple metal clusters is investigated by many different quantum mechanical theories. The longitudinal and transverse dielectric functions are the most important quantities of a quantum many- electron system which are calculated at the present work.
