Water-Soluble N-Acetyl-L-cysteine-Capped CdTe Quantum Dots Application for Hg(II) Detection
Figure 1
Effect of Hg(II) ions on the PL spectra of CdTe QDs (nm) with the concentration of Hg2+ at 0.0, 0.2, 0.5, 1.0, 2.0, 3.0, 4.3, 6.0, 8.0, and 10.0 × 10−7 M (from 1 to 10). The inset depicts the emergence of an NIR emission band on the addition of Hg(II) ions.
