a Schematic illustration of the IPG QDs and interfacial potential structure. b Synthesis schematic of core/IPG/ZnSe/ZnS QDs. c, d XRD patterns of control and IPG QDs at each stage. e, f HAADF STEM image and EDS elemental mapping of control and IPG QDs. The scale bar is 5 nm. g, h HAADF STEM image of signal control and IPG QD. The scale bar is 2 nm. i, j Smoothed EDS line scanning profiles of the corresponding signal control and IPG QD along dotted arrow.
