Besides conventional optoelectronic devices (LEDs and lasers), colloidal quantum dots (QDs) are being pursued as non-classical light sources (i.e., single-photon emitters) that may play a pivotal role in future quantum technologies, such as quantum computing, quantum cryptography, and quantum sensing.
Due to strongly reduced charge trapping on surface states and their defect-tolerant character, perovskite QDs become attractive as alternative quantum light sources. Indeed, very stable, blinking-free emission1 has been observed at cryogenic temperatures, characterized by an ultrafast radiative lifetime2,3 and a long exciton dephasing time. In addition, when organized in highly ordered three-dimensional superlattices, perovskite QDs exhibit superfluorescence (SF)4,5, a cooperative emission of individual emitters that arises due to a coherent collective coupling to a common light field.
The talk will review our recent achievements in the exploration of perovskite QDs as non-classical light sources, in particular energy-degenerate photon-pair generation from Individual CsPbBr3 quantum dots6 and future developments.
nanoGe is a prestigious brand of successful science conferences that are developed along the year in different areas of the world since 2009. Our worldwide conferences cover cutting-edge materials topics like perovskite solar cells, photovoltaics, optoelectronics, solar fuel conversion, surface science, catalysis and two-dimensional materials, among many others.
Previously nanoGe Spring Meeting (NSM) and nanoGe Fall Meeting (NFM), MATSUS is a multiple symposia conference focused on a broad set of topics of advanced materials preparation, their fundamental properties, and their applications, in fields such as renewable energy, photovoltaics, lighting, semiconductor quantum dots, 2-D materials synthesis, charge carriers dynamics, microscopy and spectroscopy semiconductors fundamentals, etc.
International Conference on Hybrid and Organic Photovoltaics
International Conference on Hybrid and Organic Photovoltaics (HOPV) is celebrated yearly in May. The main topics are the development, function and modeling of materials and devices for hybrid and organic solar cells. The field is now dominated by perovskite solar cells but also other hybrid technologies, as organic solar cells, quantum dot solar cells, and dye-sensitized solar cells and their integration into devices for photoelectrochemical solar fuel production.
Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics
The main topics of the Asia-Pacific International Conference on Perovskite, Organic Photovoltaics and Optoelectronics (IPEROP) are discussed every year in Asia-Pacific for gathering the recent advances in the fields of material preparation, modeling and fabrication of perovskite and hybrid and organic materials. Photovoltaic devices are analyzed from fundamental physics and materials properties to a broad set of applications. The conference also covers the developments of perovskite optoelectronics, including light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
The International Conference on Perovskite Thin Film Photovoltaics Perovskite Photonics and Optoelectronics (NIPHO) is the best place to hear the latest developments in perovskite solar cells as well as on recent advances in the fields of perovskite light-emitting diodes, lasers, optical devices, nanophotonics, nonlinear optical properties, colloidal nanostructures, photophysics and light-matter coupling.
