Evaluation of Williamson–Hall strain and Electrical properties in WO3@NaDCC/ITO nanoparticles thin films prepared by Hydrothermal method
Journal Title: Invention Journal of Research Technology in Engineering & Management - Year 2019, Vol 3, Issue 6
Abstract
Herein , we report the firstly, hydrothermal technique at temperature 200oC with annealing temperature at 600oC (for I hour) to depositions tungsten oxide thin films with different doping concentrations of Sodium dichloroisocyanurate NaDCC (0,2 and 4)wt% on ITO substrates with thicknesses about 100 nm , characterized with Field Emission scanning electron microscope (FESEM), electron dispersive spectroscopy (EDS) , X-ray diffraction (XRD), , hall effect measurement , direct currents and analysis to study the structural, morphological and electrical properties. The elemental composition of that nanocomposite thin films (W, O and In) determined from EDS. An X-ray diffractions pattern confirmed the formation of polycrystalline monoclinic structure for WO3/ITO and WO3@NaDCC, ITO has a cubic in structure. The Williamson–Hall plot drawn for evaluating the micro-strain and crystallite diameter. Morphology analyzed by field emission scanning electron microscopy (FESEM). The results expressed the formation of nanoparticles. In addition on it, The mechanisms of dc conductivity of un-doped WO3/ITO and doped withWO3@ NaDCC (2 and 4)wt.% /ITO thin films on at the range (303 to 473) K have discussed ,there is a decrease in conductivity with the increase in the doping concentration, and hall measurements show that all films have a negative hall coefficient and carrier concentration (n) increases with the rise of doping ratio and decreasing in carrier mobility (μH) with swelling of NaDCC
