Abstract

The optical coupling between Au nanorods (Au NRs) and chiral quantum dots (QDs) in assemblies is investigated by both experiment and theoretical calculations. The coupled optical activity in the visible-light region can be manipulated by changing either the aspect ratio of Au NRs or the size of QDs (left).

摘要

通过实验和理论计算研究了组装体中金纳米棒 (AuNRs) 和手性量子点 (QDs) 之间的光学耦合。通过改变 AuNRs 的纵横比或 QDs 的尺寸（左图），可以在可见光区域中操纵耦合的光学活性。
