Synthesis and characterization of near-infrared Cu− In− Se/ZnS core/shell quantum dots for in vivo imaging

Near-infrared (NIR) semiconductor quantum dots (QDs) represent promising fluorescent
probes for biological and biomedical imaging. CuInSe2 is a good candidate for these
applications due to its bandgap in the near-infrared and the reduced toxicity of its
components compared to other NIR QD materials (CdTe, CdHgTe, PbS, etc.). Here we
present a simple one-pot synthetic route without injection to make fluorescent sphalerite Cu−
In− Se core and Cu− In− Se/ZnS core/shell QDs. We show that the photoluminescence (PL) …

Near-infrared emitting Cu–In–Se/ZnS core/shell quantum dots: aqueous synthesis and sulfur source effects

The present study reports an aqueous synthesis approach towards Cu–In–Se/ZnS quantum
dots with emission in the near-infrared spectral range. The photoluminescence of the dots
can be effectively controlled by adjusting the sulfur source, to achieve increased quantum
yields (four times higher) and red-shifted emission peaks (from 809 nm to 830 nm).
