عنوان انگلیسی Comparative Study of Crystallite Size from XRD and TEM Results for Pure and V2O5 Doped CdO-FePO4 Composite Nanopowders
چکیده انگلیسی مقاله CdO-FePO4 composite nanopowders (CNPs) with V2O5 ions as dopants are prepared by a sol-gel technique. The as-synthesized CNPs are characterized by peak profile analysis of powder X-ray diffraction (XRD) and Transmission electron microscopy (TEM). The powder XRD analysis reveals that the prepared products are crystalline with the cubic phase of CdO. The Debye-Scherrer’s method and Williamson-Hall (W-H) plot analysis are worn to find out the separate contributions of the size of the crystal lattice and microstrain on the peak broadening of prepared CNPs. The other relevant physical parameters like microstrain and dislocation density values are determined for all the XRD peaks related to the cubic phase of CdO between 10 and 80 degrees of 2-theta values. The morphological analysis and determination of mean crystallite size are done from TEM images. The estimated crystallite size values obtained from the XRD (W-H plot and Debye-Scherrer’s method) and TEM analysis revealed that the results are highly inter-correlated. The EDX spectra confirm the presence of elements Cd, Fe, P, V, and O in the prepared sample. FT-IR study exhibited functional groups related to phosphates and oxides.
