The system Zn1-xMnxFe2O4 (x = 0, 2, and 4%) was prepared by sol–gel chemical route at 80 °C. X-Ray powder diffraction Raman spectrum analysis were used to determine the preliminary phase of obtained samples. W–H SSP plots crystallite size micro-strain surface charge morphology samples studied using zeta potential scanning electron microscope analysis, respectively. optical bandgap suggested tha...
