Growth of ZnO Nanorods on Glass Substrate by Chemical Bath Deposition

The ZnO thin films were grown onto glass slides by CBD (chemical bath deposition) from solutions containing zinc sulfate (ZnSO4), ethylenediamine (C2H8N2) and Sodium Hydroxide with continuous stirring. Structural, morphological and optical analysis of the films was studied. Scanning electron microscopy (SEM) results show compactly aggregated nanorods. The film showed high transparency about 90% and optical band gap was obtained 3.95ev for the film.
