A simple way to prepare α- and β-CoMoO 4 nanorods is reported in this paper. CoMoO 4 xH 2 O nanorod precursors were obtained using the microwave-assisted hydrothermal (MAH) method. By annealing the as-prepared CoMoO4 4 xH 2 O precursor at 600℃ for 10 min in a domestic microwave oven, α- and β-CoMoO 4 nanorods were prepared. These powders were analyzed by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), Fourier transform Raman microscopy and ultraviolet visible absorption spectroscopy (UV-vis spectra) as well as photoluminescence (PL) measurements. Based on the results, these materials revealed nanorod morphology. PL spectra obtained at room temperature for α- and β-CoMoO 4 particles exhibited maximum components around the blue light emission. The results show that the domestic microwave oven has been successfully employed to obtain α- and β-CoMoO 4 nanoparticles.
