Abstract:
Colloidal quantum dots are well-established probes for quantum optical experiments. However, they possess a limited stability toward their environment. Herein, the generation of hybrid particles composed of a high optical quality quantum dot centered in a polymer particle by means of a miniemulsion polymerization procedure is reported. This embedding strongly enhances emission intensity and photochemical stability of these single-photon emitters. At the same time, their colloidal mobile nature is not compromised.
