CdS semiconductor nanoparticles embedded in AlMCM-41 by solid-state reaction

Nanoparticles (NPs) of CdS encapsulated in AlMCM-41 were prepared by a novel technique with non-aqueous systems. The mechanical mixture of CdCl2 crystal with AlMCM-41 was heated at 773 K, followed by the H2S treatment at 373 K, resulting in the formation of Cadmium sulphide NPs with the size of 2 nm. The final product (CdSAlMCM-41) was characterized by X-ray diffraction (XRD) pattern, transmission electron microscopy (TEM), scanning electron microscopy (SEM) and UV–vis spectroscopy.
