Non-radiative optical energy transfer from a GaAs quantum well to a thinoverlayer of an infrared organic semiconductor dye is unambiguouslydemonstrated. The dynamics of exciton transfer are studied in the time-domainusing pump-probe spectroscopy at the donor site and fluorescence spectroscopyat the acceptor site. The effect is observed as simultaneous increase of thepopulation decay rate at the donor and of the rise time of optical emission atthe acceptor sites. The hybrid configuration under investigation provides analternative non-radiative, non-contact pumping route to electrical carrierinjection that overcomes the losses imposed by the associated low carriermobility of organic emitters.
