Abstract:
A series of crystals Bi(III)-VI(A)-VII(A), including the platelike crystals BiOCl, polygonal tubular crystals BiSCl, bundle-rodlike crystals Bi(19)S(27)Br(3), and BiSI, have been grown with use of mild solution routes in an ethanol system. The products are characterized by means of X-ray powder diffraction (XRD), electron diffraction (ED), scanning electronic microscopy (SEM), and Raman spectrum techniques. A possible mechanism of the reaction and of the growth of the crystals is proposed.
