Gold nanoparticles embedded in carbon film: Micromorphology analysis

摘要: Abstract In this paper the sputtered gold nanoparticles (NPs) deposited by Radio Frequency-Plasma Enhanced Chemical Vapor Deposition (RF-PECVD) method on glass substrates in trace of amorphous hydrogenated carbon (Au NPs @ a-C: H) were analyzed to study three-dimensional (3-D) surface texture. The prepared Au H films used as research materials. synthesis samples was carried out different powers from 80 120 W while all other parameters kept constant. X-ray diffraction patterns and UV–vis spectra applied structure Localized Surface Plasmon Resonance (LSPR), respectively. An atomic force microscope a non-contact mode record sample images then fractal geometry studied. numerically processed calculate Areal Autocorrelation Function (AACF), which determine anisotropy ratio Str, compute Structure (SF). log–log plots latter properties studied surfaces, such dimension D, pseudo-topothesy K. analysis 3-D texture helpful optimizing functional performance thin film.
