Synthesis and Properties of Cadmium Sulfide in Low-Polar Organic Media

Cadmium sulfide has been synthesized at heating in the medium of ethyl acetate and methyl methacrylate by interraction of cadmium trifluoroacetate with thioacetamide. At the initial stage of the synthesis colloid solutions of yellow-green color have formed. At equimolar concentrations of reactants colloid solutions stability has been sufficient for bulk methylmethacrylate thermal polymerization in the presence of benzoyl peroxide. Optically transparent polycrylate componds containing cadmium sulfide fixed in a polymer matrix have been obtained. In electronic spectra of liquid and solid solutions spectral absorption band of CdS nanoparticles has been registered. Curing of the solutions does not significantly affect the location of absorption band in spectrum. Cadmium sulfide has been educed from the solutions and analyzed by chemical methods along with methods of electron and X-ray spectroscopy. It is an amorphous compound with an incipient polytype crystal structure.
