Macromol Rapid Commun. 2013 Jul 25;34(14):1145-50. doi: 10.1002/marc.201300327. Epub 2013 Jun 7.

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.

Keywords: antibunching; colloidal quantum dots; hybrid nanoparticles; miniemulsion polymerization; single-photon emission.
