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.
胶体量子点是量子光学实验中常用的探针。然而，它们对环境的稳定性有限。本文报道了通过 miniemulsion 聚合方法生成的由聚合物颗粒中心的高光学质量量子点组成的混合颗粒。这种嵌入强烈增强了这些单光子发射器的发射强度和光化学稳定性。同时，它们胶体的迁移性质不会受到影响。
