The Hydrothermal Synthesis of ZrO2 Nanoparticles and their Optical Absorption Properties

Article Preview

Abstract:

ZrO2 nanoparticles with a diameter range of less than 10 nm are successfully synthesized with zirconium nitrate as zirconium source and stronger ammonia water as precipitant at 210 °C for 48 h via the easy hydrothermal method. The phase, the morphologies and optical absorption properties of the samples have been characterized and analyzed by X-ray diffraction (XRD), field-emission transmission electron microscopy (TEM) and ultraviolet-visible absorption spectroscopy (UV-VIS), respectively. XRD analysis shows that the phase of as obtained samples is ZrO2. TEM analysis confirms that using stronger ammonia water as precipitant instead of NaOH and the increase of the reaction temperature are in favor of the synthesis of ZrO2 nanoparticles. And UV-VIS measurements show that ZrO2 nanoparticles have a good optical absorption property.
