Pure CdS and Cu-doped thin films were deposited using the spray pyrolysis technique characterized XRD, XPS, AFM, UV-VIS spectroscopy two probe DC-conductivity measurements. 2%, 4% 6% Cu-content was used for doping. The particle size found to decrease from 28 nm 25.4 upon Cu-doping. influence of Cu-doping on stress dislocation per unit volume has been estimated XRD data. AFM images annealed show changes in morphology with increase surface roughness 25 31 Cu-6% Reflectance transmission...
Zinc sulphide (ZnS) thin film were prepared using chemical bath deposition (CBD) process and tin (Sn) doping was successfully carried out in ZnS. Structural, morphological microstructural characterization XRD, TEM, FESEM EDX. XRD SAED pattern confirms presence of hexagonal phase. Reitveld analysis MAUD software used for particle size estimation. A constantly decreasing trend observed with increasing incorporation ZnS which due to enhanced microstrain resulting incorporation. The wurtzite...
Abstract SnS thin films were grown on glass substrates by a simple route named successive ion layer adsorption and reaction (SILAR) method. The prepared using tin chloride as (Sn) source ammonium sulfide sulphur (S) source. structural, optical morphological study was done XRD, FESEM, FT-IR UV-Vis spectrophotometer. XRD measurement confirmed the presence of orthorhombic phase. Particle size estimated from about 45 nm which fitted well with FESEM measurement. value band gap 1.63 eV indicating...
A simple and cost effective chemical technique has been utilized to prepare cadmium sulphide (CdS) nanoparticles at room temperature. The sample is characterized with XRD (X-ray diffractometer), SEM (scanning electron microscope), TEM (transmission FTIR (Fourier transform infrared), EDX (energy dispersive X-rays), UV-VIS (ultraviolet visible) spectrophotometer. particle size estimated using X-ray line broadening method ~21.5 nm. While estimation, both instrumental strain was taken into...
Abstract In this research work, we have deposited cobalt oxide as pure and Ni-doped thin films using spray pyrolysis. The concentration of Ni has been changed from 0 to 6 wt% in all while other deposition parameters are fixed. characterization c X-ray diffraction (XRD), energy dispersive x-ray spectroscopy (EDX), photoelectron microscope (XPS), scanning electron (SEM), optical spectroscopy. XRD results confirm the formation Co 3 O 4 low-temperature stable phase successful doping with nickel....
Abstract Cadmium oxide (CdO) thin films were grown on glass substrates by chemical bath deposition (CBD) method for different times using cadmium acetate as cationic precursor. The structural and optical characterization was carried out XRD, TEM, UV-Vis spectrophotometer measurements. Structural analyses with XRD confirmed cubic structure of the CdO. Average particle size estimated from Rietveld refinement pattern corresponded well TEM measurement. band gap varied between 2.35 eV to 2.48...
Abstract Thin films of ZnO doped with 3 wt% Lanthanum were deposited on glass substrates using spray pyrolysis for varying thicknesses. The impact thickness the physical properties was investigated various techniques. XRD results revealed formation a mixture two phases, cubic Zinc Blende (ZB) and hexagonal Wurtzite (WU), their ratios changing based film thickness. Crystallite size measurements indicated that phase granules remained stable at 14.6 nm up to 719 nm, decreasing 14 846 while...
