Microwave Synthesis of Water-Dispersed CdTe/CdS/ZnS Core-Shell-Shell Quantum Dots with Excellent Photostability and Biocompatibility

CdTe/CdS/ZnS corre-shell-shell (CSS) quantum dots (QDs) are synthesized in the aqueous phase assisted by microwave irradiation. As-prepared CSS QDs are suitable novel fluorescent probes in biological applications because of their outstanding aqueous dispersibility, good spectral properties, excellent photostability, and favorable biocompatibility.
