With luminescence quantum efficiencies ranging from 5 to 15%, Cadmium selenide (CdSe) quantum dots (QDs) are stronger emitters than many organic fluorescent dyes. Inorganic coated ODs such as (CdSe)ZnS further increase quantum yield by fully coordinating free unbound surface electrons by reducing the occurrence of nonradiative transitions. The electron hole is confined to the QD core, while the electrons are delocalized throughout the core/shell structure. Surface modification of QDs with covalently attached dendrons offers a means to not only modify luminosity of the quantum dot,...
