  • highly porous cdo nanowires preparation based on hydroxy and carbonate containing Cadmium Compound precursor nanowires gas sensing and optical properties
    Nanotechnology, 2008
    Co-Authors: Minqiang Li

    Abstract:

    Highly porous Cadmium oxide (CdO) nanowires have been prepared by calcining the hydroxy- and carbonate-containing Cadmium Compound precursor nanowires. The large-scale precursor nanowires were synthesized through a hydrothermal method. Scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were employed to characterize and analyze the as-synthesized precursor nanowires as well as the calcined products. It was revealed that the wire-like morphology of the precursor was fundamentally retained during the process of calcination and the CdO nanowires obtained were polycrystalline with highly porous structures. In order to illustrate the formation mechanism of the porous structures, the morphology and composition evolutions of the precursor nanowires under different stages of the calcining process were further investigated via SEM, x-ray diffraction (XRD) and infrared (IR) absorbance spectroscopy. Gas sensing has been explored for the sensor device fabricated with highly porous CdO nanowires, which demonstrates that it has good response owing to its special structures and great selectivity to NOx. Furthermore, the UV–visible and photoluminescence spectra of highly porous CdO nanowires have also been investigated.

  • the series of rare earth zinc phosphides rzn3p3 r y la nd sm gd er and the corresponding Cadmium Compound prcd3p3
    IEEE Journal of Solid-state Circuits, 1999
    Co-Authors: Andre T Nientiedt, Wolfgang Jeitschko

    Abstract:

    Abstract The 12 title Compounds were prepared by reaction of the elemental components in a NaCl/KCl flux. Their isotypic crystal structures were determined for the two praseodymium Compounds from single-crystal X-ray data in the space group P 6 3 / mmc with Z =2 formula units per cell; PrZn 3 P 3 : a =404.0(1) pm, c =1997.9(6) pm, R =0.064 for 253 structure factors; PrCd 3 P 3 : a =426.5(1) pm, c =2090.6(6) pm, R =0.020 for 309 F values and 14 variables each. Large displacement parameters for one-third of the zinc, Cadmium, and phosphorus sites of both structures indicate distortions. Hence, the true symmetry of both Compounds may be lower, as is known for the closely related structure of ScAl 3 C 3 . The Cadmium and phosphorus atoms of PrCd 3 P 3 form triple-layers similar to the layers in the wurtzite-type structure of ZnS. These nets are separated from each other by the praseodymium atoms. The praseodymium and Cadmium atoms form close-packed layers of the stacking sequence ( hccc ) 2 corresponding to the atomic layers (CdCdPrCd) 2 . The phosphorus atoms occupy octahedral and trigonal bipyramidal voids of the kind Pr 3 Cd 3 and Cd 5 , respectively. Chemical bonding is briefly discussed. The praseodymium and Cadmium atoms obtain their usual oxidation numbers corresponding to the formula Pr 3+ (Cd 2+ ) 3 (P 3− ) 3 .
