To achieve the best fluorescence emission efficiency the factors of pH, temperature, and the ratio of CdS\u2010ZnS QDs to the capping agent, were investigated via a full factorial experimental design. The best fluorescence intensity was obtained at pH\u20098, temperature 80\u00b0C, and a ratio of CdS\u2010ZnS to the capping agent of 1:1.5. CdS\u2010ZnS QDs were fabricated with different capping agents: thioglycolic acid, mercaptosuccinic acid, and L\u2010cysteine.
