Structural transformation of ZnO quantum dots to ZnO/ZnS core–shell quantum dots and fluorescence color shift from yellow to blue induced by interfacial sulfurization

What is it about?

We improved tiny glowing particles made of zinc oxide by adding a thin outer layer of another material called zinc sulfide. This change makes the particles glow blue instead of yellow and shine more clearly. The method we used could help create better materials for lights, solar panels, and other tech that uses light.
