Figure 4

(a) Photoluminescence spectra of MPA-CdTe QDs (0.86 × 10−6 mol l−1) at pH 10 and pH 4.5, and the photoluminescence of MPA-CdTe in the presence of chitosan at pH 4.5, in methanol/water (1:3 v-v). (b) Photoluminescence lifetime of MPA-CdTe QDs in the absence and presence of chitosan (1.0 g l−1) at pH 4.5. The signal of IRF (blue) is the response of the instrument.
