The development of organic materials for electronic applications has seen a dramatic and sustained growth over the last decade due to their unique characteristics and capabilities. There is rapidly growing interest in the use of organic materials as radiation sensors, where they offer the potential for low cost, large area detectors with unique physical properties. Recent studies have included semiconducting polymers, single crystal organics and perovskites, and hybrid systems involving organic scintillator/photosensor combinations. In this workshop we aim to bring together all those interested in organic materials for radiation detection, with a view to sharing the current state-of-the-art, identifying common challenges to address, and building a cohesive research community. Topics will cover the material properties and device physics of the following systems: Polymer and long-chained molecules Single crystal organic materials Scintillation/photosensor hybrid organic systems Organic perovskite materials The workshop will consist of invited overview talks by recognised experts in the field of organic materials and devices.
