Abstract
The hexagonal structure of zinc oxide (ZnO) and silver-doped zinc oxide (Ag: ZnO) nanocrystallites at room temperature was prepared using the Co-Precipitation process. Capping agent Glycerol was used to synthesize nanocrystallites. The Structural characterization such as Powder X-ray Diffraction (XRD), Scanning Electron Microscope (SEM), and Energy Dispersive X-ray Spectroscopy (EDS) was performed. The De-bye Scherer formula can be used to calculate the average size and strain also calculated using W-H graphical method. The Powder X-ray Diffraction results compared with JCPDS results. Scanning Electron Microscopy were used to study the morphological nature of the prepared sample and the Study of EDAX energy dispersive x-rays analysis used to verify the elements in the sample. The effect of silver dopant was analyzed using average size determination and strain determination methods. Excitation wavelengths of prepared samples were analyzed using UV-visible method. The porosity effect, volume fraction, hydration reaction of prepared samples were analyzed and reported.
