From: One-step fabrication of biocompatible chitosan-coated ZnS and ZnS:Mn2+ quantum dots via a γ-radiation route

Figure 2

TEM images, EDS spectra, size distribution, and XRD patterns of QDs fabricated in different conditions. (a) TEM image of ZnS QDs (no chitosan coating); (b) TEM image of CS-ZnS (0.1% CS); (c) TEM image of CS-ZnS (2% CS); (d) TEM image of CS-ZnS:Mn2+ (0.1% CS); (e) XRD patterns corresponding to (b) and (d); insets in (b) and (d) are EDS spectra, HRTEM images, and particle size distribution histograms, respectively.
