“…Luminescent QDs are typically core/shell structures, which are produced by coating the luminescent semiconductor NCs with a wider band-gap inorganic semiconductor shell to passivate surface nonradiative recombination sites more effectively than organic ligands. Within the device, the shell is also key to efficiently confine the excitons to the QD core and sufficiently separate QDs, minimizing luminescence quenching by Förster resonant energy transfer of excitons to nonradiative recombination sites. − For more detailed information on the different aspects of the QD-LEDs, the reader is referred to several reviews and book chapters on the topic. ,− …”

This review captures the synthesis, assembly, properties, and applications of copper chalcogenide NCs, which have achieved significant research interest in the last decade due to their compositional and structural versatility. The outstanding functional properties of these materials stems from the relationship between their band structure and defect concentration, including charge carrier concentration and electronic conductivity character, which consequently affects their optoelectronic, optical, and plasmonic properties. This, combined with several metastable crystal phases and stoichiometries and the low energy of formation of defects, makes the reproducible synthesis of these materials, with tunable parameters, remarkable. Further to this, the review captures the progress of the hierarchical assembly of these NCs, which bridges the link between their discrete and collective properties. Their ubiquitous application set has cross-cut energy conversion (photovoltaics, photocatalysis, thermoelectrics), energy storage (lithium-ion batteries, hydrogen generation), emissive materials (plasmonics, LEDs, biolabelling), sensors (electrochemical, biochemical), biomedical devices (magnetic resonance imaging, X-ray computer tomography), and medical therapies (photochemothermal therapies, immunotherapy, radiotherapy, and drug delivery). The confluence of advances in the synthesis, assembly, and application of these NCs in the past decade has the potential to significantly impact society, both economically and environmentally.

“…With these definitions and context in mind, we review in depth the role luminescent QDs have played in energy transfer (ET), within the specific context of QD-based bioconjugates and their biological applications. Although QDs are clearly at the intersection of several scientific disciplines, limiting this review to biological contexts helps narrow its scope and separate it from the vast role that the combination of QDs and ET are playing within solar power and energy harvesting, electronics, photonics, and several other related fields. − …”

Luminescent semiconductor quantum dots (QDs) are one of the more popular nanomaterials currently utilized within biological applications. However, what is not widely appreciated is their growing role as versatile energy transfer (ET) donors and acceptors within a similar biological context. The progress made on integrating QDs and ET in biological configurations and applications is reviewed in detail here. The goal is to provide the reader with (1) an appreciation for what QDs are capable of in this context, (2) how this field has grown over a relatively short time span, and, in particular, (3) how QDs are steadily revolutionizing the development of new biosensors along with a myriad of other photonically active nanomaterial-based bioconjugates. An initial discussion of QD materials along with key concepts surrounding their preparation and bioconjugation is provided given the defining role these aspects play in the QDs ability to succeed in subsequent ET applications. The discussion is then divided around the specific roles that QDs provide as either Förster resonance energy transfer (FRET) or charge/electron transfer donor and/or acceptor. For each QD-ET mechanism, a working explanation of the appropriate background theory and formalism is articulated before examining their biosensing and related ET utility. Other configurations such as incorporation of QDs into multistep ET processes or use of initial chemical and bioluminescent excitation are treated similarly. ET processes that are still not fully understood such as QD interactions with gold and other metal nanoparticles along with carbon allotropes are also covered. Given their maturity, some specific applications ranging from in vitro sensing assays to cellular imaging are separated and discussed in more detail. Finally a perspective on how this field will continue to evolve is provided.

“…Numerous compounds, mostly oxides, phosphates, nitrides, fluorides, were considered as suitable phosphors for constructing W-LED sources, see for example [11][12][13][14][15][16][17][18][19][20][21]. Furthermore, there is the intensive research aiming to find efficient red phosphors to construct white LED based on near-ultraviolet (UV) LED chips coated with RGB tri-color phosphors.…”
