Plasmonic nanoparticles have drawn tremendous interest in the scientific community due to their unique ability to interact with light via localized surface plasmons. Understanding the delicate interplay between particle morphology, composition and optical properties is of utmost importance in optimizing particle design for numerous applications. While single-particle spectrally-resolved measurements can reveal insights into the optical properties, electron microscopy (EM) can be utilized to study structural features. With the advances in complex nanoparticles' geometries, however, 2D EM techniques are no longer sufficient and the need for determining the 3D structure arises. In this talk, I will show examples of different strategies for correlating the optical properties of single plasmonic nanoparticles with their 3D morphology obtained from electron tomography. In particular, I will highlight how the combination with single-particle optical techniques opens up pathways for additional information inaccessible to electron-based techniques. Finally, I will discuss how quantified electron tomography is indispensable in unravelling structural changes in plasmonic nanoparticles driven by pulsed laser irradiation and our recent progress towards studying these modifications in situ inside the electron microscope.
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.
