Quantum dots (QDs) have a complex internal structure

Caption

CdZnSe/CdZnS quantum dots (QDs) have a complex internal structure that extends the lifetime. (A) TEM analyses reveal a zinc selenide-rich core interior and a cadmium sulfide shell exterior. (B) Time resolved emission reveals lifetime tunability by simple alterations to the QD structure. The lifetimes can be 10-times greater compared with similar materials.
