Colloidal nanocrystals (NCs) with radial-position-controlled doping were synthesized to study the effect of the binding symmetry around Mn2+ dopant. For the four samples ZnSe:Mn/ZnSe, ZnSe/ZnS(2 ML):Mn/ZnS(2 ML), ZnSe/ZnS(1 ML):Mn/ZnS(2 ML), and ZnSe:Mn/ZnS(2 ML), which were in sequence of binding asymmetry around Mn2+ dopant, their photoluminescent (PL) peak showed gradual red-shift (579 to 599 nm) and the PL lifetime became monotonously shorter (0.57 to 0.31 ms), while, as indicated in the… CONTINUE READING
