Low-dimensional metal halides are a large family of compounds that consist of 2D, 1D, or 0D anionic metal halide framework coupled with organic or inorganic countercations. Due to the quantum confinement in low-dimensional structures, excitons can be localized with sufficiently large binding energies, enabling luminescence at room temperature. In hybrid organic-inorganic metal halides, both the inorganic metal halide anion and the organic cation can be functionalized to act as luminescent centers. The broad structural and compositional flexibilities of low-dimensional metal halides offer tremendous opportunities to optimize optical properties for light emitting applications. High photoluminescent quantum efficiencies (PLQEs) up to 100% have been reported for a number of 0D metal halides [e.g., (C4N2H14Br)4SnBr6 (95%), [(C6H5)4P]2SbCl5 (100%), Cs3Cu2I5 (83%)]. In this talk, we show first-principles calculations of electronic structure and excitonic properties (including excitation/emission energies, exciton self-trapping, etc.) in low-dimensional metal halides, and discuss the emission mechanism, the material chemistry that affects the PLQE, and the prospect of using these materials as phosphors and scintillators.
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.
