Properties of Cadmium-(bis)dodecylthiolate and Polymeric Composites Based on It

We study the thermo-physical and photoluminescence (PL) properties of cadmium-(bis)dodecylthiolate (Cd(C(12)H(25)S)(2)). Significant attention is drawn to characterization of Cd(C(12)H(25)S)(2) by different methods. The laser-induced PLs of Cd(C(12)H(25)S)(2) and Cd(C(12)H(25)S)(2)/(polymethyl metha...

Sumario:We study the thermo-physical and photoluminescence (PL) properties of cadmium-(bis)dodecylthiolate (Cd(C(12)H(25)S)(2)). Significant attention is drawn to characterization of Cd(C(12)H(25)S)(2) by different methods. The laser-induced PLs of Cd(C(12)H(25)S)(2) and Cd(C(12)H(25)S)(2)/(polymethyl methacrylate) (PMMA) composites are studied. Samples of Cd(C(12)H(25)S)(2)/PMMA are synthesized by the polymerization method. Ultraviolet (UV)-pulsed laser irradiation of the samples under relatively small fluences leads to the formation of induced PL with the maximum near the wavelength of 600 nm. This process can be attributed to the transformation of Cd(C(12)H(25)S)(2) within the precursor grains. Another PL peak at 450–500 nm, which appears under the higher fluences, relies on the formation of CdS complexes with a significant impact of the polymer matrix.
