ABSTRACT

ZnO nanorod arrays have been grown on ITO glass substrates which were pre-coated

with ZnO nanoparticles by using a low cost and low temperature chemical solution

method. The structural and optical properties of ZnO nanorod arrays were investigated

using scanning electron microscopy (SEM) and photoluminescence (PL) techniques. It

was demonstrated that the introduction of annealed ZnO nanoparticles seed layer is

required for the formation of well-aligned ZnO nanorods. The ZnO nanorod arrays with

a diameter of 40-70 nm and a length of 200-300 nm were obtained. Besides, a strong

UV emission peaked at 386 nm in the PL spectrum revealed the good crystal quality of

ZnO nanorods.
