Intense Visible Luminescence in CdSe Quantum Dots by Efficiency Surface Passivation with H2O Molecules
Figure 1
(a) The PL spectra of the QDs cooled by different solvents and additional heat treatment, (b) the change in PL spectra after additional heat treatment of the QDs in different solvents, (c) the ratio of PL peak intensity calculated from the experimental date of (b). The inset of (a) is the photograph of core CdSe QDs under room light.
