Abstract Pure CdS nanoparticles and Fe-doped quantum dots (Cd₁₋ₓFeₓS, where x = 0.0, 0.03, 0.06, 0.09, 0.12) were successfully synthesized using the co-precipitation method. X-ray diffraction (XRD) analysis confirmed cubic phase structure of without additional peaks, indicating effective incorporation Fe ions into lattice. The crystallite size exhibited a gradual increase with increasing content. High-resolution transmission electron microscopy (HR-TEM) revealed well-defined spherical...
Polyvinyl alcohol-polypyrrole (PVA/PPY) composite polymer films were prepared by chemical polymerization. Cobalt chloride CoCl2·6H2O was used at different concentrations as doping (x = 0.2–1.0 g). The produced characterized X-ray diffraction (XRD), Infrared spectroscopy (IR) and transmission electron microscopy (TEM). optical properties of all studied, where the absorption decreases with increasing x value in both VIS (500–700 nm) UV (200–400 regions. calculated energy gaps (Eg1 Eg2) found...
Graphite powder was introduced into polyvinylidene fluoride via the solution mixing technique. The composites were then subjected to hot compression molding. effect of dispersion graphite particles and electrical conductivity investigated. Solution enabled homogeneous within matrix as revealed by transmission electron microscopy. X-ray diffraction Fourier transform infrared spectroscopy analysis that incorporation induced α-phase fluoride. DC results showed increased with an increase in...
A thin film of Gd3+ doped Mn–Cr ferrite the chemical formula MnCr0.5Gd0.02Fe1.48O4 was prepared by pulsed laser deposition from bulk sample at room temperature. The optical absorption, transmission and reflection spectra were measured discussed in wavelength range 300 to 2500 nm. parameters calculated following single oscillator model. band gap found be 2.75 eV, dispersive energy electric dipoles estimated using Wemple–Di Domenico relation 6.395 while oscillating dipole is 4.997 eV....
In the present study copper and iron oxides loaded TiO₂ catalysts are prepared by deposition-precipitation method (DP) photocatalytic efficiency of these tested for degradation Rose Bengal dye (Acid Red 94) under sunlight. The characterized XRD, TEM UV-vis diffuse reflectance spectral analysis. It is interesting to note that rutile form commercial competently converted into anatase after loading Cu, Fe Cu-Fe on as evident from XRD This result consistence with obtained in spectra. analysis...
