Abstrakt

Cryst. ZrO2 nanoparticles were prepd. from zirconium isopropoxide by slow hydrolysis and subsequent hydrothermal treatment of solns. contg. various amts. of sodium hydroxide at 180 C. Whereas moderately basic solns. lead to the formation of nanoparticles of monoclinic ZrO2 with plate-like morphol., and nanoparticles of the cubic ZrO2 high-temp. polymorph with diams. of approx. 5 nm were obtained from strongly basic solns. The morphol., structure and properties of as-synthesized nanoparticles were characterized using HRTEM, XRD, Raman spectroscopy, UV-vis, PL spectroscopy and BET measurements. The formation of both, the monoclinic and the cubic polymorph, was confirmed by electron microscopy and Raman spectroscopy. The crystallinity and morphol. of the resulting ZrO2 nanoparticles can be adjusted by the choice of the reaction conditions. The cubic ZrO2 nanoparticles have a high surface area (300 m2/g) and exhibit a strong photoluminescence in the UV region.
