Structural, morphological, and optical properties of flowerlike Sm-doped h-MoO3 nanorods
An effective hydrothermal process was used to synthesize both pure h-MoO _3 and Sm-dopedh-MoO _3 (0 M%, 0.5 M%, 1.5 M%, and 2.5 M%) compositions. The x-ray diffraction (XRD) approach was used to determine the prepared materials' structural properties and phase purity. The structure and crystall...

| description | An effective hydrothermal process was used to synthesize both pure h-MoO _3 and Sm-dopedh-MoO _3 (0 M%, 0.5 M%, 1.5 M%, and 2.5 M%) compositions. The x-ray diffraction (XRD) approach was used to determine the prepared materials' structural properties and phase purity. The structure and crystallite size of the samples were found to be significantly influenced by the doping concentration. Field Emission Scanning Electron Microscopy (FESEM) micrographs revealed that the nanorods are randomly aligned with flower-like hexagonal shapes, where the average length and diameter range from ∼ 1.9–2.5 μm and ∼ 300-600 nm, respectively. Williamson–Hall (W–H) and Debye–Scherrer (D–S) methods compare the variation of structural characteristics, including dislocation density, crystallite size, and lattice strain. Energy Dispersive x-ray measurement (EDX) demonstrates the expected contents of the respective compositions. The Fourier Transform Infrared Spectroscopy (FTIR) was used to describe the vibrational behavior of chemical bonds, and the detected peaks demonstrate the production of h-MoO _3 . In FTIR, there were noticeable variances in peak intensities and wavenumbers between the undoped and doped samples due to the presence of various functional groups; the detected peaks support the XRD result that the prepared h-MoO _3 is pure and maintains a hexagonal shape with doping. The Diffuse Reflectance Spectra (DRS) indicate the optical bandgap decreased due to doping, where the optimum bandgap was obtained for 0.5 M% Sm doped in h-MoO _3 . Thus, the significant influence of Sm doping on the structural, morphological, and optical properties of h-MoO _3 nanorods indicates the possibility of application in the field of photocatalytic dye degradation, hydrogen generation, and magnetic behaviors. |
