Abstract
► Optical properties of Mn-doped Zn x Cd 1− x S NCs were studied. ►The NCs with PL QY up to 29% were synthesized based on MnS/ZnS/CdS structure. ► The composition was controlled by growing various thicknesses CdS layer. ► The PL band of NCs was composed by the emissions of Mn 2+ ions and defect states. Optical properties of Mn-doped Zn x Cd 1− x S nanocrystals were studied by steady-state and time-resolved photoluminescence (PL) spectroscopy. The doped nanocrystals with PL quantum yield up to 29% were synthesized by growing a thin ZnS layer on the MnS core and then growing a CdS layer with different thicknesses using nucleation-doping strategy. The absorption band edge of Zn x Cd 1− x S nanocrystals was tuned from 425 to 475 nm by growing the CdS layer with various thicknesses under different Zn/Cd molar ratios to vary the composition. The PL band of Mn-doped nanocrystals was found to originate from emissions of Mn 2+ ions and defect states.
