Raman spectra recorded with the 455 nm laser line for pure CdS and Zn0.2Cd0.8S solid solutions: (a) pure CdS (synthetized by coprecipitation method); (b) pure CdS-SQ (synthetized by assisted sonochemical method); (c) Zn0.2Cd0.8S; (synthetized by coprecipitation method); and (d) Zn0.2Cd0.8S-SQ (synthetized by assisted sonochemical method).
