Abstract
A core/shell nanoparticle with enhanced emission comprises a fluorescent conjugated polymer core that is encapsulated by an amphiphilic block copolymer shell. The core/shell nanoparticle structure confines the electronic charge to improve quantum yield and is water soluble to enable low-cost and environmentally friendly processing.
