The doping of aluminum (Al3+) and the co-doping of aluminum (Al3+)/fluoride (F−) into cadmium sulfide-montmorillonite were investigated. The Al3+ doping was achieved by the reactions between Al3+/Cd2+-montmorillonite and an aqueous solution of sulfide (S2−). The doping of F− was conducted by the reactions between the Al3+ doped sample and an aqueous solution of sodium fluoride (NaF) at room temperature...
Silica layer was deposited on the spherical Co3O4 particles, which were prepared by the thermal decomposition of cobalt nitrate, by the hydrolysis and condensation of tetraethylorthosilicate (TEOS) in the presence of cetyltrimethylammonium bromide (CTAB) in alcohol (methanol, ethanol, propanol or butanol). The products were characterized by X-ray diffraction (XRD), scanning and transmission electron...
The hybridization of cadmium selenide and organically modified clay mineral, cetyltrimethylammonium–montmorillonite, was investigated by a simply colloidal process. The hybrid was characterized by powder X-ray diffraction, thermal analysis, transmission electron microscopy, as well as Raman, UV–visible and photoluminescence spectroscopies. The blue-shift of the absorption onset and the appearance...
