Environmentally friendly, highly efficient, and large stokes shift-emitting ZnSe:Mn²⁺/ZnS core/shell quantum dots for luminescent solar concentrators.

ABSTRACT: In this study, heavy-metal-free orange light-emitting ZnSe:Mn²⁺/ZnS doped-core/shell (d-C/S) quantum dots (QDs) were synthesized using a nucleation doping strategy. To synthesize high quality d-C/S QDs with high photoluminescence (PL) quantum yield (QY), the Mn²⁺ concentration was optimized. The resulting ZnSe:Mn²⁺(5%)/ZnS d-C/S QDs showed a high PL QY of 83.3%. The optical properties of the synthesized QDs were characterized by absorption and PL spectroscopy. Their structural and compositional properties were studied by X-ray diffraction, transmission electron microscopy, and energy dispersive X-ray spectroscopy. After doping Mn²⁺ into a ZnSe core, the ZnSe:Mn²⁺/ZnS d-C/S QDs showed a large Stokes shift of 170 nm. The ZnSe:Mn^2+</
