In the last decade, metal halide perovskites (MHPs) have rapidly emerged as one of the most interesting classes of materials, with strong light-matter interactions, tunable luminescence over the entire visible spectrum and large electron-hole diffusion lengths, which have proven extremely useful in a wide range of scientific and technological disciplines. The subsequent development of material preparation using low-temperature solution-based strategies has allowed the same material to be obtained as nanocrystals (NCs) with high control over size and shape and further increase their optical properties tunability via dimensional confinement. Also importantly, this novel material preparation approach further extended LHPs applicability thanks to the possibility of processing directly from solution to realize functional thin films, nanocomposites or simple solution-based devices. In their NCs form, LHP have been widely applied as efficient emitters in artificial light sources, overcoming the limits of resolution and color purity of single crystals, or as high-Z materials efficiently interacting with ionizing radiation for scintillators, showing performances comparable or even higher than their large macroscopic crystal counterparts. In this talk, I will focus on our recently developed strategies for engineering LHP-NCs for different application: from high-power direct and down-converting light emitting devices (LEDs) to potential biomedical applications. I will present the different approaches that have been adopted to specifically tune the spectroscopical, chemical and physical properties of LHP NCs for these application, pursued via chemical modification (compositional tuning, post-synthesis surface treatments) of physical confinement (encapsulation into mesoporous silica nanoparticles).
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.
