Background/Objective: ZnO nanoparticle synthesis by sol gel method and its characterization to find out the morphology of the particles.

Methods/Statistical analysis: Sol-gel technique was used to prepare zinc oxide nanoparticles. The characterization was done by X-Ray diffractive (XRD), UV- Visible spectroscopy and field emission scanning electron microscopy (FE-SEM). X-Ray diffraction (XRD) was used to find out the particle size and FE-SEM image was used to determine its morphology.

Findings: pH 9 offers better morphology and good crystalline nature. The morphology can be changed by varying the solvent ratio.

Improvements/Application: Gas sensor application.
