UV IRRADIATION EFFECTS ON DLC:Ag FILMS: CHARGING OF THE PLASMONIC NANOPARTICLES

摘要

Effects of the UV irradiation on optical properties of hydrogenated diamond like carbon (DLC) nanocomposite films containing Ag nanoparticles (DLC:Ag) deposited by direct current (DC) unbalanced reactive magnetron sputtering were studied in 180-1100 nm range. Additional annealing experiments were conducted. It was determined that both heating and UV irradiation affected transmittance and reflectance spectra of DLC:Ag films. However since these cause opposing effects, there is a competition between the heating and UV activated Ag nanoparticle charge processes.
