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

Figure 4

Optical transmittance of samples prepared with the Cd concentration indicated in the figure. Comm refers to the spectrum of a sample prepared with CdS powder from Sigma-Aldrich. The inset shows representative fitting to the model of direct transitions between parabolic bands along with the experimental spectrum.
