Structural, Optical, and Magnetic Properties of NiMoO(4) Nanorods Prepared by Microwave Sintering
We report on the structural, optical, and magnetic properties of α,β-NiMoO(4) nanorods synthesized by annealing the NiMoO(4):nH(2)O precursor at 600°C for 10 minutes in a domestic microwave. The crystalline structure properties of α,β-NiMoO(4) were investigated using X-ray diffraction (XRD), Fourier...

Sumario: | We report on the structural, optical, and magnetic properties of α,β-NiMoO(4) nanorods synthesized by annealing the NiMoO(4):nH(2)O precursor at 600°C for 10 minutes in a domestic microwave. The crystalline structure properties of α,β-NiMoO(4) were investigated using X-ray diffraction (XRD), Fourier transform infrared (FTIR), and Raman (FT-Raman) spectroscopies. The particle morphologies and size distributions were identified by field emission microscopy (FE-SEM). Experimental data were obtained by magnetization measurements for different applied magnetic fields. Optical properties were analyzed by ultraviolet-visible (UV-vis) and photoluminescence (PL) measurements. Our results revealed that the oxygen atoms occupy different positions and are very disturbed in the lattice and exhibit a particular characteristic related to differences in the length of the chemical bonds (Ni-O and Mo-O) of the cluster structure or defect densities in the crystalline α,β-NiMoO(4) nanorods, which are the key to a deeper understanding of the exploitable physical and chemical properties in this study. |
