Abstract :
Zinc oxide (ZnO) nanorods have been deposited onto glass substrates by integrating inexpensive successive
ionic layer adsorption and reaction (SILAR) at room temperature. The concentration of precursor solution was varied
in order to study its effect on structural, morphological and optical properties. The X- ray diffraction (XRD) patterns
showed that the films deposited are polycrystalline with preferential orientation along (101) plane. Scanning electron
microscopy (SEM) images show the formation of vertical ZnO nanorods with diameter and length of ~120 nm and
~400 nm respectively. The optical study showed that films are highly transparent in the visible region with an average
transmission of about ~85%. The optical band gap degreased from 3.30 eV to 3.075 eV on increase in molar
concentration.
