Abstract

The authors investigate the temperature dependence of exciton transfer from a single InGaN quantum well (QW) donor to colloidal CdS nanocrystal quantum dot acceptors and obtain an optimum transfer efficiency of 65% at 60 K. Time and spectrally resolved measurements reveal that the transfer efficiency is dominated by the interplay between exciton localization and nonradiative recombination intrinsic to the QW.
