Synthesis and Optical Properties of Thiol Functionalized CdSe/ZnS (Core/Shell) Quantum Dots by Ligand Exchange
Figure 3
The UV/Vis absorption (a) and PL emission (b) spectra peaks are slightly red shifted with the gradual addition of ZnS shell layers on CdSe core. (c) High-resolution aberration-corrected electron microscope (ACEM) examination of a typical CdSe/ZnS (core/shell) QDs.
