- ... Hierarchical SiO₂–QDs@SiO₂ (QDs = CdTe, PbTe or PbS) nanostructures have been prepared by an integrated synthesis and self-assembly strategy using 3-mercaptopropionic acid (MPA) to stabilize the QDs and NaOH to control the self-assembly of QDs on the SiO₂ nanobead carriers. 3–10 nm QDs covered with a 1–2 nm SiO₂ shells were separately embedded on the surface of 50 nm SiO₂ nanobead carriers, result ...
