Forster resonant energy transfer (FRET) within the luminescent donor-acceptor complexes is a powerful tool for biomedical fluorescent detection platforms, optical sensors. Luminescent semiconductor colloidal nanocrystals or quantum dots are ideal candidates for FRET donors due to very broad spectral range of optical absorption and narrow photoluminescence bands, whose spectral position can be easily tuned either by size or chemical composition of quantum dots. Additionally, the shape of semiconductor nanocrystals can be varied from spherical (quantum dots) to elongated (nanorods), nanowires, tetrapods. Based on the experimental results, here we discuss how to construct the efficient FRET complexes with luminescent CdSe nanocrystals, how the shape of CdSe nanocrystals may affect on the FRET efficiency in the nanocrystal-dye complexes, how to control with FRET the radiative and non-radiative pathways in double band-emitting ZnSe quantum dots doped with Mn ions.
