This Brief presents a complete study of the generalized theory of Forster-type energy transfer in nanostructures with mixed dimensionality.

This Brief will focus on the functional uses and applications of FRET, starting with the derivation of FRET in the assemblies of nanostructures and subsequently giving application cases for biologists, physicists, chemists, material scientists, engineers, and those in many other fields whoever would like to FRET as a tool.
