3D mapping of compositional gradients of core-shell structures in AgInxGa1-xS2 quantum dots by atom probe tomography
S through a cation exchange process, ensuring structural and chemical compatibility with the inner shell. Our findings uncover the internal architecture and nanoscale elemental distributions of quaternary QDs, providing guidance for the future development of QDs.
