Nonradiative energy transfer from indirect bandgap InAs/AlAs quantum dots (QDs) to direct bandgap InAs/AlGaAs QDs was studied by steady-state and transient photoluminescence. We demonstrate that long excitonic lifetime in donor InAs/AlAs QDs allows one to extend the efficient exciton energy transfer between coupled QDs to distances up to 9 nm.
