Abstract
Spectra of optical density of granulated 2-nm-thick gold films deposited on the surface of thin films of amorphous hydrogenated carbon (a-C:H) on quartz substrates are investigated. A shift of the peak corresponding to the localized surface plasmon resonance toward the shorter wavelengths by 32 nm upon an increase in the optical bandgap of the a-C:H films from 0.8 to 2.4 eV is demonstrated. Simultaneously, an increase in intensity and narrowing of the plasmon-resonance band in spectra of gold nanostructures is observed. This fact indicates that formation of the granulated gold films on the surface of a-C:H films depends on the specific structural properties of the latter.
