MOCVD of Molybdenum Sulphide Thin Film Via Single Solid Source Precursor Bis-(Morpholinodithioato-s,s’)-Mo

引用

Journal of Modern Physics 2011年第5期2卷 341-349页

作者： Bolutife Olofinjana gabriel egharevba Bidini Taleatu Olumide Akinwunmi Ezekiel Oladele Ajayi 不详

A single solid source precursor bis-(morpholinodithioato-s,s’)-Mo was prepared and molybdenum sulphide thin film was deposited on sodalime glass using Metal Organic Chemical Vapour Deposition (MOCVD) technique at deposition temperature of 420?C. The film was characterized using Rutherford Backscattering Spectroscopy (RBS), Ultraviolet-Visible Spectroscopy, Four point probe technique, Scanning Electron Mi-croscopy (SEM), X-ray Diffractometry (XRD) and Atomic Force Microscopy (AFM). A direct optical band gap of 1.77 eV was obtained from the analysis of the absorption spectrum. The sheet resistance was found to be of the order of 10P–5P ΩP–1P?cmP–1P. SEM micrographs of the films showed the layered structure of the film with an estimated grain size that is less than 2 μm while XRD indicates parallel orientation of the basal plane to the substrate surface.

Synthesis and Characterization of CdS, ZnS and CdZnS Nanoparticles Embedded in Polystyrene

引用

Journal of Modern Physics 2014年第5期5卷 257-266页

The nano dispersions (colloids) of Cadmium Sulfide, Zinc Sulfide and Cadmium Zinc Sulfide were prepared by modified metathesis reaction between CdCl2, ZnCl2 and Na2S. The prepared sulfides were embedded in polystyrene to form nano-composites. The size, morphology and composition of the nanoparticles on the surface of the composites were examined by using UV/VIS Spectroscopy, Scanning Electron Microscopy (SEM), High Resolution Transmission Electron Microscopy (HRTEM), Energy Dispersive Spectroscopy (EDS) and Particle Induced X-ray Emission (PIXE). The UV-spectrum shows a shift in the band gap towards high energy while the High Resolution Transmission Electron Microscope (HRTEM) analysis shows well resolved nanoparticles with particle sizes between 2-10 nm. The SEM shows that the nanoparticles are in form of nano clusters. The blue shift of the absorption band makes it possible to evaluate the size of the nanocrystallites, which is in agreement with that obtained from HRTEM. The composition as revealed by the EDS shows that the ratios of Cd:S, Zn:S and Cd:Zn:S are approximately 23:20, 58:42 and 32:35:33, respectively. The PIXE spectra confirmed the presence of expected elements and also reveal the presence of impurities.
