The pH value of solution was varied to study the surface morphology and particle size variations in ZnO. The X-ray diffraction peaks of all the samples corresponds to hexagonal wurtzite structure of ZnO and the data also shows significant variation in particle size as well as the lattice strain of ZnO nanoparticles with respect to pH values of the solution. The Scanning Electron Microscopy (SEM) images show different morphology at different pH values. Hexagonal shaped nanorod structures were observed at pH value of 7 and 9, and plate like structures were observed “at pH values 10.5 and 12.5. Fourier Transform Infrared Spectroscopy (FT-IR) confirms the formation of ZnO at ~450 cm-1. UV-visible Spectroscopy (UV-vis) analysis shows symmetrical shift in the absorption edge towards the lower wavelength or higher energy region with decrease in particle size of the ZnO samples.
