Cadmium oxide nanoparticles CdO NPS has been prepared by laser ablation in ethanol at 600 pulses and 600 mJ as laser energy. The structural, optical, and morphological properties of the cadmium oxide CdO thin film deposited on a glass substrate have been studied. X-ray diffrac-tometer (XRD 6000, Shimadzu, X-ray, diffractometer) with Cukα radiation at a wavelength of ( = 0.154056 nm) was utilized to investigate the structural properties of CdO NPs. The optical absorption of colloidal CdO NPs was measured using a spectrophotometer (Cary, 100 cans plus, UV-Vis-NIR, Split Beam Optics, Dual detectors) in the range of (200–900) nm. The morpholo-gy of the CdO NPs was investigated by using AFM (AA 3000 Scanning Probe Microscope). The thickness of the films was measured using ellipsometer (Angstrom sun Technologies Ins).

The phytosynthesis of n-type Cadmium Oxide Nanoparticles reduces the toxicity of the substance and makes it Eco-friendly. This Eco-friendly biosynthesis of CdO NPs was synthesized for the first time from the Queen of herbs, Ocimum Sanctum (holy basil).The biosynthesized Cadmium oxide was prepared using Ocimum leaf extract as a reductant and Cadmium Chloride and hydroxide as cadmium and oxide source materials by Co- Precipitation method. Thus obtained Cadmium Oxide Nanoparticles were characterized by different techniques such as X-ray diffraction (XRD), Fourier Transform infrared spectroscopy (FTIR), Scanning electron microscope (SEM),Energy dispersive X-ray spectroscopy(EDS) to study the structural and morphological properties. XRD pattern exhibited the formation of face centered cubic structure of CdO NPs with an average crystalline size of 11.5nm .The chemical bond formation of CdO NPs were confirmed by FTIR spectrum in the range of (400-4000cm-1). The SEM micrographs revealed the predominant formation of Cauliflower shape with a particle size in the range of 61-142nm. The high purity of the biosynthesized nanoparticles were confirmed by EDS analysis. Further it was tested against gram positive and gram negative bacterial strains and showed significant antibacterial activity. This biosynthetic research study opens an innovative window to progress our understanding of how CdO NPs shows resistance to different bacterial strains.

NiO/BiFeO3 thin film has been deposited on Pt/Ti/SiO2/Si substrate by sol-gel method. The structure of thin film is analyzed by X-ray diffraction, and the result of X-ray diffraction shows that a perovskite crystal structure can be well-grown on Pt/Ti/SiO2/Si substrate. In addition, the surface morphology is characterized by a scanning probe microscope, and the image of scanning probe microscope indicates a good crystalline quality of NiO/BFO thin film. Moreover, the current-voltage properties are also measured by a semiconductor characterization system, and the stable and reproducible nonvolatile resistive switching characteristic for the memory application have been clearly observed in Pt/NiO/BiFeO3/Pt structure, which could be attributed to the formation and rupture of filament localized in NiO thin layer.

OCLI is a leading manufacturer of thin films for optical and thermal control applications. The determination of thin film and substrate topography can be a powerful way to obtain information for deposition process design and control, and about the final thin film device properties. At OCLI we use a scanning probe microscope (SPM) in the analytical lab to obtain qualitative and quantitative data about thin film and substrate surfaces for applications in production and research and development. This manufacturing environment requires a rapid response, and a large degree of flexibility, which poses special challenges for this emerging technology. The types of information the SPM provides can be broken into three categories:(1)Imaging of surface topography for visualization purposes, especially for samples that are not SEM compatible due to size or material constraints;(2)Examination of sample surface features to make physical measurements such as surface roughness, lateral feature spacing, grain size, and surface area;(3)Determination of physical properties such as surface compliance, i.e. “hardness”, surface frictional forces, surface electrical properties.

Abstract In this paper, we report oxidation time effect on highly porous silver oxide nanowires thin films fabricated using ultrasonic spray pyrolysis and oxygen plasma etching method. The NW’s morphological, electrical, and optical properties were investigated under different plasma etching periods and the number of deposition cycles. The increase of plasma etching and oxidation time increases the surface roughness of the Ag NWs until it fused to form a porous thin film of silver oxide. AgNWs based thin films were characterized using X-ray diffraction, scanning electron microscope, transmission electron microscope, X-ray photoemission spectroscopy, and UV–Vis spectroscopy techniques. The obtained results indicate the formation of mixed mesoporous Ag2O and AgO NW thin films. The Ag2O phase of silver oxide appears after 300 s of oxidation under the same conditions, while the optical transparency of the thin film decreases as plasma etching time increases. The sheet resistance of the final film is influenced by the oxidation time and the plasma application periodicity. Graphic abstract

Cdo Nanoparticles

Cadmium oxide (CdO) nanoparticles was synthesized from an aqueous solution containing metal nitrate as a precursor and polyvinyl pyrrolidone (PVP) as a capping agent by simple thermal-treatment method. The as-synthesized sample has been calcined at various temperatures from 500 to 650 °C to remove the organic matters. The structure and morphology of the calcined oxide nanoparticles have been examined by X-ray diffraction (XRD) and transmission electron microscopy (TEM), respectively. The results obtained supports the fact that the thermal treatment method utilized for the synthesis of CdO nanoparticles is certainly a very simple and low cost technique that requires no additional chemicals.
