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 of the luminescence band at the wavelength of 565. nm for cadmium selenide-cetyltrimethylammonium-montmorillonite were thought to be caused by the restricted microenvironment of cetyltrimethylammonium-montmorillonite that affected the particle size and growth of the cadmium selenide nanoparticles. Transmission electron micrograph showed that the cadmium selenide nanoparticles with the diameters of 7.00-10.10. nm were intercalated in the interlayer space. The enhancement of the emission intensity of the stored hybrid indicated that solid surface of cadmium selenide in the adsorbed state could be tailored by cetyltrimethylammonium-montmorillonite.
