Metathesis microwave synthesis, Rietveld refinement and optical studies of metal orthovanadates, MVO4 (M = Cr, Fe, Co, Ni, Cu)

Metathesis microwave synthesis (MMS) of metal orthovanadates (MNO4), M= Cr, Fe, Co, Ni, Cu) are realized with byproduct NaCl having high lattice energy driven in the forward direction of the MMS reaction based on ionic exchange The synthesis procedure is applied at 850 W powers in a domestic oven for a short time as 10 minutes The structural, morphological and optical properties of synthesized powders are determined by powder X-ray diffraction (XRD), Rietveld analysis, fourier transform infrared spectroscopy (FTIR), scanning electron microscopy/energy dispersive X-ray analysis and photoluminescence spectroscopy (PL) The unit cell parameters and crystal systems of the products are identified by Rietveld refinement method one by one.
