Hydrogenated silicon (Si:H) thin films were deposited at a selected argon diluting ratio under varied RF power density and the influence of it on nanocrystallization was studied by XRD, FTIR and Raman spectroscopy.
Boron-doped nanodiamond (NCD) films were synthesized on silicon substrates by microwave plasma chemical vapor deposition (MPCVD) technique. The effect of vacuum annealing on the field emission characteristics of NCD films has been investigated. The surface morphology and quality of films was characterized by scanning electron microscope (SEM) and Raman spectroscopy. The SEM images clearly reveal formation...
Photodetection techniques in the non-fluorescent regime when combined with nanotechnology offer promising new angles in diagnosing diseased conditions over conventional fluorescence-based imaging. In this study, we developed two types of spherical gold nanostructures: gold nanoshells and gold nanoparticles and used them to enhance optical backscattering signal in confocal reflectance microscopy and...
The effects of position of substrates in flames, preparation time, stability of flames and catalyst precursors on carbon nano fibers are investigated in ethanol catalytic combustion. For investigating the effects of these influence factors on carbon nano fibers, several sets of controlled experiments are performed, such as different position of substrates, different preparation time, stable and unstable...
Size quantised cadmium sulphide (CdS) nanocrystalline thin films with different particle sizes and stoichiometric ratios were successfully grown on indium tin oxide substrates using an aqueous synthetic route. The effect of cadmium (Cd) to sulphur (S) ratio on the optical properties of CdS nanocrystalline films was investigated using EDAX, UV-vis spectroscopy, photoluminescence and Raman spectroscopy...
