Description	Journal: Journal of Physics D: Applied Physics The spatial control of the nano-emitters in novel light harvesting platforms offers great potential for the manipulation of the excitonic interaction amongst the donor-acceptor pairs of energy transferring agents. In this work, we report colloidal quantum dot loaded electrospun nanofibers as a light harvesting platform to study the excitonic interaciton among them. The donor emission lifetime modified from 12.46 ns to 7.45 ns with the change in the ratio of green and red quantum dots in the nanofiber, as a result of confining acceptor quantum dots in close proximity. The spectrally narrow emitter luminescent nanofiber platforms have further been investigated for their potential of white light generation. The hybrid platform of blue LED integrated electrospun nanofibers has been shown to demonstrate a correlated color temperature (CCT) of 3632.5K, luminous efficacy of optical radiation (LER) value of 307.7 lm/Wopt along with color rendering index (CRI) value of 60. The control on the physical confinement and excitonic interactions of the nano emitters would potentially open up new pathways towards realization of the surface emitting platforms with high surface to volume ratio.
