Modification of spontaneous emission from CdSe/CdS quantum dots in the presence of a semiconductor interface.
The spontaneous-emission lifetime of CdSe/CdS core-shell quantum dots was studied as a function of the distance between the dots and a polished Si surface. The experimental results reveal a significant modification of the spontaneous-emission rate of the quantum dots by the Si surface.
