Effect of PVA surface capping on the optical absorption of ZnO nanorods grown via chemical bath deposition
Abstract
ZnO nanorods were grown via chemical bath deposition in a glass cover slip with a seed layer deposited using spray pyrolysis of Zn(CH3COO)2·2H2O solution. After annealing the grown nanorods, the surface was capped using PVA solution which was prepared one day prior. SEM images and FTIR analysis were done to confirm the presence of PVA to the ZnO nanorods which is known to attach at the zinc vacancy defect. Upon confirmation, both the as-grown and PVA-capped ZnO nanorods had their absorbance measured for comparison using UV-Vis spectroscopy. Larger change in the absorbance was found at the wavelength corresponding to the energy of the defects.
