|Title:||Up- and down-conversion cubic zirconia and hafnia nanobelts||Authors:||Jiang, C.
|Issue Date:||17-Dec-2008||Citation:||Jiang, C., Wang, F., Wu, N., Liu, X. (2008-12-17). Up- and down-conversion cubic zirconia and hafnia nanobelts. Advanced Materials 20 (24) : 4826-4829. ScholarBank@NUS Repository. https://doi.org/10.1002/adma.200801459||Abstract:||A direct and scalable approach, based upon a thermal decomposition method under normal atmospheric pressure was introduced, for growing well-defined single-crystalline cubic ZrO2 and HfO2 nanobelts with controllable structural compositions and novel optical properties. A solution of ZrCl4 and YCl3.6H2O in ethanol was first treated with sodium hydroxide to yield a viscous gel mixture. The mixture was transferred into a 15 mL Teflon-lined autoclave and heated at 140°C for 24h. The as-synthesized ZrO2 precursors are composed of Zr(OH) 4 as characterized by Fourier transform IR and thermal analysis. XRD patterns of the YSZ samples obtained with less Y3+ content show a mixture of monoclinic, tetragonal, and cubic phases. The down-conversion emission spectrum that is independent of dopant ions show a peak centered at 470nm, corresponding to band gap emission of the host.||Source Title:||Advanced Materials||URI:||http://scholarbank.nus.edu.sg/handle/10635/95384||ISSN:||09359648||DOI:||10.1002/adma.200801459|
