Abstract

We, herein, report a facile green synthetic route for the gram-scale synthesis of high-quality thiol-derivatized zinc selenide quantum dots (QDs) using selenourea as the source of selenium at a relatively low temperature. The one-pot synthesis of colloidal dots has been achieved by selenizing zinc (II) acetate in a non-coordinating solvent medium. The structural, microstructural, optical, thermal, textural and electronic properties of the as-synthesized monodisperse ZnSe dots have been investigated in detail. We attribute the observed green emission from the dots to the donor-acceptor pair (DAP) recombination of photoexcited charge carriers. All the findings of the investigation indicate that ZnSe QDs hold great promise as a nanoscale emissive probe to unveil cellular dynamics beyond the capabilities of conventional imaging techniques. © 2024 John Wiley & Sons Ltd.
