摘要：

A simple approach was introduced to enhance the photostability of CuInS2@ZnS core@shell quantum dots (QDs) by doping aluminium into the ZnS shell. Aluminium in the as-prepared QDs was oxidized to Al2O3, which formed a passivation oxide layer that effectively prevents photo-degradation of QDs during long-term light irradiation.
