Synthesis of CdS Nanocrystals by Employing the By-Products of the Anaerobic Respiratory Process of Desulfovibrio alaskensis 6SR Bacteria

Figure 5

Normalized Raman spectra of the samples prepared with a solution with Cd concentration of (a) 170 ppm, (b) 200 ppm, (c) 300 ppm, and (d) 400 ppm. The inset shows the comparison of the Raman spectrum of the sample prepared with a solution with Cd concentration of 170 ppm with that obtained using a commercial CdS sample.
