“…As in Table 1. Figure (2) show images SEM films Au precipitated on substrate polymer (PVA) and prepared sputtering in a manner different thickness where the thickness was increase granules size increasing this is consistent with the researcher [10]. where it can be note increasing the square root of the rate of surface roughness (RMS) with increasing thickness, as shown in Table (2) where the increase refers to the increase in surface roughness of the films and this confirms the results of examination of XRD, which refers to increase the granular size and thus surface roughness increase film thickness record, increasing the thickness of the top lead to increased homogeneity of the film and this corresponds to the researcher [10].…”

“…This work was conducted in several tests to determine the effects of fixed pressure, and increase the time period for the deposition lead to increase the sputtering rate, thereby increasing the thickness of the film [10] on the structure and morphology Au films prepared sputtering plasma glow discharge on the polymers (PVA)substrate. These tests are represented by:…”

In this research, preparation of Au films on poly vinyl alcohol (PVA) substrates by using plasma direct current glow discharge sputtering (FT-IR)results for poly vinyl alcohol showed matching the sites of the active groups of the polymer with its chemical composition X-ray diffraction (XRD) showed that the thin films had a polycrystalline while the surface roughness was diagnosed using an atomic force microscopy (AFM)the where the results showed that the roughness increased from (30.099-55.221)nm with increasing the thickness from (90-195)nm. Scanning electron microscope(SEM)showed that nanoparticles with a spherical shape the particles aggregates to form larger clusters with increased film thickness.

“…Another characteristic very important in the case of the Au thin film is the optical response of the samples. In particular the theoretical absorbance peak of gold is situated around 650 nm [11]. In the case in which samples present morphological differences and when the wavelength of the incident radiation is higher than the structure present, we expected a different behavior due to the LSPR (Localized surface plasmon resonance).…”

Metallic nanostructures are widely studied because of their peculiar optical properties. They possess characteristic absorbance spectra with a peak due to plasmonic resonance. This feature is directly dependent on the nanostructures shape, size, distribution and environment surrounding them. This makes them good candidates for a variety of applications, such as localized surface plasmon resonance sensing (LSPR), surface-enhanced Raman scattering (SERS) and photovoltaics. A well established technique used to create nanoisland on flat substrates is performing a thermal treatment after the deposition of a thin metal film. While the most widely investigated metal in this context is gold, we have extended our investigation to palladium, which is interesting for sensing applications because it has an excellent hydrogen absorption ability. The morphological properties of the nanoisland depend mainly on the starting thickness of the deposited layer and on the annealing parameters, temperature and duration. The deposition and annealing process has been investigated, and the resulting samples has been tested optically and morphologically in order to optimize the structures in view or their application for sensing purposes.

“…The unique properties of gold at the nanoscale Ð for instance: low electrical resistivity, inertness and resistance to sulfur-based tarnishing Ð also render it suitable for implantation due to its biocompatibility, when compared with most other metals [14,15]. Recent advances in synthesis techniques and biomolecular engineered gold nanoparticles have led to medical applications in the areas of biosensors, gene and photothermal therapy, targeted drug delivery, tissue engineering, and disease therapy [16][17][18][19].…”
