Description

An initial investigation of the optical properties of silver doped amorphous carbon films is presented in this study. The effects of alternate variations of irradiation energies and fluences in relation to the surface plasmon resonance (SPR) were studied. The study exhibits that the shifts in energy and fluences suggested a change in the overall optical absorbance and consequently on the plasmonic properties of the thin films.
