Structural and optical analysis of nanostructural CuCrO₃ perovskite by sol–gel method

Abstract CuCrO 3 perovskite structure synthesized via cost-effective sol–gel method successfully as confirmed by X-ray diffraction (XRD) with smaller crystallite size has been reported. EDS confirmed copper chromite perovskite single phase with no extra impurity peak existence. Agglomerated grains resulting average particle size of 9.6 nm as determined from SEM micrographs. PL spectra shows electron transition from VB to CB whereas Raman spectra shows D and G band presence within spectra pointing towards existence of functional groups within structure. Bandgap value of 4.02 eV is calculated from UV–vis spectra. In order to calculate Eu, which is calculated to be 0.960 Ev. All these properties suggested synthesized material applicability as an optoelectronic perovskite material.
