Cyclic voltammetry studies of cadmium zinc sulfide

deposition potential for cadmium zinc sulfide thin film Figure 4 shows the CV for 0 01 M ZnCl 2 0 01 M CdCl 2 and 0 01 M Na 2 S 2 O 3 mixture at pH 2 The forward scan remained low until 0 80 V versus Ag/AgCl The rapid increase in the cathodic current after this potential could be due to the formation of cadmium zinc sulfide compound
