LASER & PHOTONICS REVIEWS R

Abstract In the past two decades, semiconductor quantum dots and wires have developed into new, promising classes of materials for next-generation lighting and display systems due to their superior optical properties. In particular, exciton–exciton interactions through nonradiative energy transfer in hybrid sys-tems of these quantum-confined structures have enabled ex-citing possibilities in light generation. This review focuses on the excitonics of such quantum dot and wire emitters, par-ticularly transfer of the excitons in the complex media of the quantum dots and wires. Mastering excitonic interactions in low-dimensional systems is essential for the development of better light sources, e.g., high-efficiency, high-quality white-light gen-eration; wide-range color tuning; and high-purity color genera-tion. In addition, introducing plasmon coupling provides the abil-ity to amplify emission in specially designed exciton–plasmon nanostructures and also to exceed the Förster limit in excitonic interactions. In this respect, new routes to control excitonic path-ways are reviewed in this paper. The review further discusses research opportunities and challenges in the quantum dot and wire excitonics with a future outlook.
