Thioglycolic acid stabilized CdTe/CdS core/shell quantum dots were synthesized in an aqueous solution. The photostability of the CdTe/CdS core/shell quantum dots to UV irradiation is investigated. The optical spectra were measured after different intervals of irradiation time. The irradiation led to an improvement of the quantum yield of quantum dots. With extending of the irradiation time (18 h), the CdTe quantum dots aggregated, but CdTe/CdS core/shell quantum dots were stable. Therefore, the presence of CdS shell on the surface of quantum dots increases their photostability. The high photostability of QDs is important in biology applications.

Keywords: Quantum dots, CdTe/CdS, Core/shell structure, Aqueous synthesis, Photostability
