Structural and optical properties of Mn2+-doped ZnCdS/ZnS core/shell quantum dots: New insights in Mn2+ localization for higher luminescence sensing

Sami Rtimi

The synthesis methods (one-or two-pot) of stable Mn2+ doped ZnxCd1-xS and ZnxCd1-xS/ZnS quantum dots are reported in this study with a quantum yield (QY) of -60% in anhydrous and -30% in aqueous media for Mn2+ photoluminescence (PL). Mn2+-localization in t ...
