Triplet generation at the CdTe quantum dot/anthracene interface mediated by hot and thermalized electron exchange for enhanced production of singlet oxygen

Abstract

Triplet energy transfer (TET) from semiconductor quantum dots (QDs) to molecular triplets has potential applications in photon up-conversion and singlet oxygen generation. Here, we have constructed a complex consisting of...

Size-Regulated Hole and Triplet Energy Transfer from CdSe Quantum Dots to Organic Acceptors for Enhancing Singlet Oxygen Generation

“…Previous studies have demonstrated that the TET process from QDs to molecular acceptors is very complicated. − Although several mechanisms have been proposed, including Dexter-type TET, electron or hole transfer-mediated TET, and trap state-mediated TET, − it is still being debated. In addition, a higher TET efficiency has been observed in small size QD-sensitized systems, and different mechanisms for this observation have been proposed .…”
