Abstract

original image

Multicolor emitting microspheres with three dimensionally controlled nanostructures are produced via a simple and efficient method. Location control and separation of the quantum dots (QDs) within the microspheres are achieved by a supramolecular assembly of block copolymer micelles to control the Förster resonance energy transfer efficiency between the different-colored QDs.
