The synthesis of SiO2@CdS nanocomposites using single-molecule precursors
Monteiro, Olinda C.; Esteves, Ana Catarina C.; Trindade, TitoA chemical method for preparing cadmium sulfide nanocrystals over silica surfaces is reported. This is a one-step synthetic method involving the chemical degradation of alkyldithiocarbamato complexes of cadmium in the presence of submicrometric SiO2 particles. The X-ray powder diffraction patterns of the SiO2@CdS nanocomposites show diffraction peaks consistent with the presence of hexagonal CdS. Visible spectr...
Use of dialkyldithiocarbamato complexes of bismuth(III) for the preparation of ...
Monteiro, Olinda C.; Nogueira, Helena I. S.; Trindade, Tito; Motevalli, MA range of bismuth(III) dithiocarbamato complexes were prepared and characterized. The X-ray crystal structures of the compounds [Bi{S2CN(CH3)(C6H13)}3] (1) and [Bi{S2CN(CH3)- (C6H13)}3(C12H8N2)] (2) are reported. The preparation of Bi2S3 particulates using a wet chemical method and involving the thermalysis of Bi(III) dialkyldithiocarbamato complexes is described. The influence of several experimental paramete...
