CdSe/CdS量子点及量子点@聚苯乙烯荧光微球的制备
Preparation of CdSe/CdS Quantum Dots and Quantum Dots@Polystyrene Fluorescent Microspheres
摘要
Abstract
In order to improve the encapsulation efficiency of quantum dots in polystyrene microspheres,CdSe/CdS core-shell quan-tum dots were firstly prepared by thermal cycling single precursor coupling method.The quantum dots@polystyrene fluorescent mi-crospheres were then successfully obtained by embedding the CdSe/CdS core-shell quantum dots in polystyrene microspheres using ligand exchange and emulsion polymerization.The results indicated that the fluorescent quantum yield of the prepared core-shell quantum dots was more than 90％.Using the method of ligand exchange,not only the solubility of the core-shell quantum dots was improved,but also the encapsulation efficiency of quantum dots in polystyrene microspheres was increased to 87％.This might be useful in improving the detection sensitivity of quantum dots fluorescent microspheres in immunofluorescence assay.关键词
