Abstract : Various methods of obtaining fine colloidal precipitates of cadmium sulfo-selenides in SiO2 gel matrices are described. These materials, which are of interest in optoelectronic applications, can be prepared by diffusion of various reactants in wet gels. The influence of different preparative parameters on the diffusion characteristics the possibility of obtaining distribution gradients and, in particular, the interest of sonocatalysis (ultrasonic irradiation) are briefly presented.
