چکیده مقاله:

We report the growth and characterization of Cu nanoparticles thin film of on glass substrate by pulse laser deposition method. The Cu thin film prepared with different energy 50, 60, 70, and 80 mJ. The energy effect on the morphological, structural and optical properties were studied by AFM, XRD and UV-Visible spectrophotometer. Surface topography studied by atomic force microscopy revealed narrowed size distributions, with particle sizes ranging from 65.8 to 90.09 nm. The results showed the Average Gran Size increased with increasing energy and RMS roughness increased with increasing energy. X-ray diffraction showed nanostructure phase With ( 2q = 43.297, 50.433 degree). The results show that by increasing thickness, the copper films crystallinity in (111) direction increases. Optical properties measurements showed transformation from metallic properties of bulk Cu to semiconductor properties when formed by sort of nanostructure evidenced by the formation of optical energy gap about (3.45 to 3.89 eV) with different conditions. When the thickness of samples is increased the crystallinity and the mean grain size improved.

Characterization of nanostructured SnO2 thin film coated by Ag nanoparticles

Nanostructured SnO2 thin films were prepared using Electron Beam-Physical Vapor Deposition (EB-PVD) technique. Then Ag nanoparticles synthesized by laser-pulsed ablation were sprayed on the films. In order to form a homogenous coated of SnO2 on the glass surface, it was thermally treated at 500°C for 1 h. At this stage, the combined layer on the substrate was completely dried for 8 h in the air...

Synthesis of Novel Thin-Film Materials by Pulsed Laser Deposition

Pulsed laser deposition (PLD) is a conceptually and experimentally simple yet highly versatile tool for thin-film and multilayer research. Its advantages for the film growth of oxides and other chemically complex materials include stoichiometric transfer, growth from an energetic beam, reactive deposition, and inherent simplicity for the growth of multilayered structures. With the use of PLD, a...

Characterization of Nd: Yag Laser Radiation Effects on Ti6Al4V Physico-Chemical Properties: An In Vivo Study

The effect of a Nd: YAG laser (1064 nm) has been studied on Ti6Al4V alloy in terms of optical and physical parameters for biomedical applications. The superior surface microhardness hardness (i.e. 377 VHN) is attributed to grain refinement associated with laser melting and rapid solidification. The electrochemical property, mainly pitting corrosion resistance, has been carried out in Hanks salt...
