Water-Soluble N-Acetyl-L-cysteine-Capped CdTe Quantum Dots Application for Hg(II) Detection
Figure 3
Effect of other metal ions on the PL of NAC-capped CdTe QDs (nm). The concentrations of Li+, Na+, K+, Ca2+, Mg2+, and Zn2+ were 1 × 10−3 M. The concentration of Cd2+ was 1 × 10−4 M. The concentrations of Pd2+, Fe3+, and Cu2+ were 4 × 10−6 M. The concentration of Hg2+ was 6 × 10−7 M.
