Abstract

Using sol gel method, samples were grown and with changing the amount of precursor, pH of solvent was controlled. Thus, four samples were produced with the different pH. Atomic force microscopy (AFM), energy-dispersive X-ray (EDX) analysis and x-ray diffraction (XRD) structural characterization were performed on samples which showed smooth surface with zinc oxide structure. Transmittance (drying and annealing) and photoluminescence spectra and also band gap calculations showed that optical property depends on pH of solvent. Magnetic property of samples was done by magnetic force microscopy (MFM) and quantum design. Results show that the magnetic property may depend on changing of pH of solvent..
