Fabrication and Characterization of thin films of ZnO and MWNTs dispersed in DMF

Zinc Oxide thin films are deposited on the glass substrate of different concentration of zinc and their effect on the structural and morphological properties were investigated. Zinc acetate dehydrate, di-ethanolamine and ethanol were used as the precursor, stabilizer and solvent respectively. A molar ratio of 1:1 is maintained between Di-ethanolamine to Zinc acetate. XRD was used to analyze the crystal structure and orientation of the films. The patterns in the XRD show that the ZnO films were polycrystalline with wurtzite hexagonal structure. The ZnO thin film with 0.75M concentration has the better crystalanity as in intrinsic nature a constituent atoms, ions or molecules will be in definite arrangement. The surface morphology of the ZnO thin film was observed by scanning electron microscope (SEM). The SEM images show that they are homogenous, continuous and spindle like shape. Multi walled carbon nanotubes (MWCNT) thin film was deposited on a glass substrate and their effects on structural and morphological properties were investigated. MWCNT was dissolved in Di-Methyl Formamide. Using scanning electron microscope (SEM) surface morphology of MWCNT thin film was observed.
