Why Surface Chemistry Matters for QD–QD Resonance Energy Transfer
ACS Energy Letters, 2017 Resonance energy transfer (RET) has been shown to occur in films of semiconductor quantum dots (QDs) with variation in QD composition and size. When coupled with charge carrier transfer, RET could provide a complementary strategy for light harvesting in QD based solid state photovoltaic devices.
