title: Controllable optical activity of gold nanorod and chiral quantum dot assemblies.
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).
