Abstract
We demonstrate a one-pot synthesis of CdSeZnS/ZnS alloyed blue (482 nm) and green (526 nm) quantum dots in organic solvents. During the formation of core/shell quantum dots (QDs), a blue-shift was observed after coating with ZnS shell. A wavelength tuning of alloyed QDs emission is obtained by the different ratios of Se-precursor in the cores. Silica surface was formed to make water-soluble alloyed QDs. The alloyed QDs were characterized by absorbance and photoluminescence (PL) spectroscopy and PL quantum yield.
