X-ray imaging scintillators and detectors play a critical role in numerous everyday life applications, including medical radiography, high-energy physics research, and security inspections. Despite its importance, current X-ray imaging technologies are not fully equipped to meet the growing demands for flexible, cost-efficient, and environment-friendly solutions. To overcome the limitations associated with traditional imaging scintillators, recent research efforts have focused on developing lead-free luminescent materials. Of particular interest are Cu(I) complexes, which exhibit excellent photoluminescence behavior, a facile synthesis process, and a high atomic number, making them an ideal candidate for X-ray imaging applications. Our work focuses on developing a low-dimensional Cu(I) organometallic halide and utilizing it as an imaging scintillator for real-life X-ray imaging. By utilizing the 0D Cu(I)-based imaging scintillators, we successfully obtained detailed images of both biological and non-biological objects, with a low detection limit of 458.3 nGy/s and high resolution of 16.8 lp/mm [1]. This study not only provides a design roadmap for Cu(I) luminescent materials, but also highlights their potential for high-impact real-life X-ray imaging applications in medicine and security.

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.
