Synthesis and Characterization of Na Doped ZnO Rods Grown by Simple Chemical Method

Abstract

In this study, the effects of Na doped on the structure, morphology, and optical properties of the ZnO films deposited on glass substrate were investigated. The films were synthesized on glass substrates via a simple chemical method. Undoped and Na-doped ZnO films were obtained from an aqueous solution of the Zinc nitrate hexahydrate (Zn(NO3)2·6H2O), Sodium Nitrate (NaNO3) and hexamethylenetetramine-HMT (C6H12N4). Characterization of the films was examined using a Scanning electron microscope (SEM) and X-ray diffractometer (XRD), Ultraviolet-Visible spectrophotometer (UV-Vis) and X-Ray Photoelectron (XPS). The structure, morphology, and optical properties of the films were presented. The wurtzite ZnO films showed rod arrays morphology. The optical band gap increased with the doping of Na metal. The result shows that Na addition affected the properties of the ZnO films.

Facile growth of high transmittance ZnO micro-rod clusters on indium tin oxide by a wet-chemical synthesis method

“…The lattice parameters determination for the ZnO micro-rod clusters include the measurement of d value of (002) plane to determine the c lattice parameter and the measurement of d value of (100) plane to determine the a lattice parameter ( h or k being different from zero). The lattice parameters a and c (literature value of a = 3.2050 Å and literature value of c = 5.1380 Å 32 ) listed in Table 1 were determined using the (100), (002), and (101) reflections, according to equation (8). The equation (8) 23 iswhere ( hkl ) is the reflection plane and a and c are lattice parameters.…”
