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.
通过将铝掺杂到ZnS壳层中，引入了一种简单的方法来提高CuInS2@ZnS核壳量子点（QDs）的光稳定性。所制备量子点中的铝被氧化为Al2O3，形成了一层钝化氧化层，可有效防止量子点在长期光照下发生光降解。
