A simple room temperature chemical route, which was based on the reaction of zirconium nitrate and hexamethylenetetramine as a starting material in aqueous medium at 576 K for 24 hr., was proposed for the synthesis of zirconium dioxide (ZrO2) nanoparticles. The structural properties of prepared material were characterized by using X-ray diffraction and Field emission scanning electron microscopy. The optical properties of material were studied by using photoluminescence and Ultra-Violet spectroscopy. X-ray diffraction and Field emission scanning electron microscopy shows that material was crystalline with particles size in nano range. Ultra-violet spectra indicated that the as-synthesized ZrO2 nanoparticles has a direct band gap of 4.82 eV and also is a usual value for the photo catalytic activities in UV-Vis light.
