Figure 1. (A) Variations of PL QY and peak wavelength; (B) absorption spectra; and (C-F) TEM images of green InP/ZnSe/ZnS QDs synthesized with different Zn precursor types of ZnX2 (X = Cl, Br, I) and Zn(OA)2 for growth of ZnSe inner and ZnS outer shell. The double shell thicknesses of ZnSe/ZnS for individual QDs are also depicted in (C-F). The scale bars in (C-F) are all 20 nm. PL: Photoluminescence; QY: quantum yield; TEM: transmission electron microscopy; InP: indium phosphide; QDs: quantum dots.
