Controlled light emission by nanoencapsulation of fluorophores in thin films of diblock copolymer micelles

Abstract

Controlled light emission is generated from thin films of fluorophores that are encapsulated in diblock copolymer micelles. The mutual distance between the two fluorophores is regulated by utilization of the nanometer-sized micellar structure, which enables or restricts energy transfer between the fluorophores. This encapsulation method results in single or simultaneous light emission (see figure).
