Investigations on synthesis, characterization and humidity sensing properties of ZnO and ZnO-ZrO composite nanoparticles prepared by ultrasonic assisted wet chemical method.

In the present investigations, Zinc oxide (ZnO) and ZnO-ZrO composite nanoparticles were synthesized by ultrasonic assisted wet chemical method to investigate their structural, optical and humidity sensing properties. The synthesized nanoparticles were characterized by the techniques like X ray diffraction (XRD), UV-Vis absorption spectroscopy, Scanning Electron Microscopy (SEM) and Energy Dispersive Spectroscopy (EDS). XRD and EDS were employed to confirm the phase formation and phase purity respectively.
