XRD pattern shows a cubic zinc-blende phase of ZnSe as well as core/shell QDs. TEM images of ZnSe-I and QDs are shown in the inset.
Linear absorption for ZnSe as well as core/shell QDs. The inset shows the schematic of electron energy levels in ZnSe QDs.
Open aperture -scan traces of (a) ZnSe-I and (b) QDs at an input intensity of .The insets show the scaling for 3PA.
