Advanced characterization and computational design
PNovel materials and devices for photon and ionizing radiation detection
This symposium will focus on novel materials and devices both for photonic (UV-Vis) and for high energy applications. These include functional materials like organic and perovskite as photodetectors or scintillators, together with high-Z materials sensitive to X/ γ-rays and charged particles. The symposium will discuss the performance and challenges of new materials for use as both direct and indirect radiation detectors.
Scope:
This symposium will focus on novel materials and devices for the sensitive detection of photons and for the conversion of high energy ionizing radiation. The aim of the symposium is to bring together the European Community working in this field, to foster the exchange of knowledge, identify the emerging trends, and launch new collaborations.
The focus will be mainly on organic semiconductors and metal halide perovskites, although the symposium is open to the discussion of alternative materials. The topics will be focused on electromagnetic radiation detection beyond the visible range. Novel developments on active materials both for direct detection and for indirect detection (scintillators) will be covered by the symposium.
Organic semiconductors: organics have demonstrated performance similar to inorganic semiconductors in the visible spectrum, but there is an important gap to fill in the NIR, which will be addressed in this symposium. Organic semiconductors exhibit distinct qualities and functionalities that make them ideal for ionizing radiation detection. Notably, they offer tissue-equivalent, biocompatible properties for X-ray/photon dosimetry applications and demonstrate effectiveness in fast neutron detection owing to their hydrogenic composition. As scintillators, organic materials have fast kinetics, great customizability and easy shaping, but suffer from poor radiation stability and low detection efficiency. To overcome these limitations, increasing attention is being paid to the development of nanocomposite scintillators consisting of polymeric matrices doped or coated with nanocrystals of high atomic number compounds.
Metal halide perovskites: perovskites are promising for the detection of high energy photons (UV-DUV) and for ionizing radiation detectors. Offering the advantage of low-energy synthesis, both inorganic perovskites and hybrid perovskites exhibit significant potential for detecting X-rays and gamma radiation. In particular, lead halide perovskites have emerged also as promising scintillators, prized for their efficient color-tunable radioluminescence, and high radiation hardness. The symposium will address the device integration of conventional perovskite materials as well as the preparation of novel, enhanced perovskite formulations. Discussions will encompass the development and characterization of perovskite single crystals, thick films, and nanoparticles, all within the context of applications for high energy photons and ionizing radiation detection.
