Halide perovskites and their structural analogs, perovskitoids, are increasingly recognized for their outstanding photoluminescence properties in addition to their semiconductor performance. While three-dimensional (3D) and two-dimensional (2D) halide perovskites have been extensively studied for photovoltaic applications, their potential in light-emitting devices is equally compelling, driven by their long carrier lifetimes, efficient radiative recombination, and compositional tunability. Perovskitoids, with their diverse structural motifs, enable further control over dimensionality, exciton confinement, and emission bandwidth. By rationally selecting organic spacer cations, we can fine-tune crystal packing and stabilize architectures that favor enhanced photoluminescence and suppressed nonradiative pathways. Notably, heterostructures composed of perovskitoid-perovskite layers exhibit reduced ion migration and improved exciton confinement, leading to more stable and efficient emissive behavior. A prime example is the 2D perovskitoid (organic cation)₈Pb₇I₂₂, which demonstrates high-quality film formation and effective surface passivation, crucial for light-emitting device fabrication. In parallel, the rhenium chalcohalide Rb₆Re₆S₈I₈ exemplifies a new class of photoluminescent cluster-based materials. It exhibits broad emission from 1.01 to 2.12 eV with a quantum yield of 42.7% and a long PL lifetime of 77 μs at room temperature. The solubility of Rb₆Re₆S₈I₈ in polar solvents allows for solution processing into thin films, enabling the fabrication of prototype LEDs and highlighting its promise for future optoelectronic applications.
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.
