Synthesis and characterization of nanocrystalline zinc sulfide via zinc thiobenzoate-lutidine single-source precursor
摘要:
ZnS nanocrystals were prepared both in the form of mesoporous powder and thin films by one step thermal decomposition technique from a single-source procure (SSP) [Zn(SOCPh)(2)Lut(2)center dot H2O]. The final product was characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), N-2 adsorption-desorption isotherm, UV-Vis absorption spectroscopy and photoluminescence (PL) study. Structural analyses of the prepared ZnS revealed the formation of cubic crystallites with diameters around 5 and 10 nm for the thin films and powder materials, respectively. On the other hand, the powder form showed mesoporous nature (type IV isotherm) with an average pore diameter of 37.9 angstrom and BET specific surface area of 51.73 m(2)/g. (C) 2011 Elsevier B. V.
