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.

Quantum dot (QD)-based probes for multiplexed determination of heavy metal ions

Microchimica Acta, 2020
Heavy metal contamination is a major global concern and additive toxicity resulting from the exposure to multiple heavy metal ions is more pronounced than that induced by a single metal species.

Synthesis and applications of metal-organic framework–quantum dot (QD@MOF) composites

, 2016
The combination of the high surface areas, microporosity and tuneable compositions of metal-organic frameworks (MOFs) with the desirable photo-physical behaviour of semiconductor nanoparticles or quantum dots (QDs), allows the preparation of composite ...

Polydimethylsiloxane-Based Quantum Dot Color Conversion Layers for QD-OLED Applications [PDF]

Micromachines
Quantum dot (QD)-based color conversion layers are key components in QD-OLED displays because they can provide high color purity and simplified pixel architectures by converting blue emission from OLEDs into red or green light.
