Abstract
Zinc oxide is of particular interest for its use in many applications: varistors, gas sensors, etc. The purpose of this study is to obtain zinc oxide nanoparticles by using the polyol method. The obtained powder was analysed by X-ray diffraction and scanning electron microscopy. Using the X-ray diffraction, one can see that the ZnO is present in a single crystalline phase. The SEM images show spherical particles with a size less than 25 nm.
