We report on the use of organic semiconducting single crystals (OSSCs) as direct ionizing radiation detectors that directly convert the X-ray photons into an electrical signal, thanks to their stability, good transport properties and large interaction volume. X-ray detectors, based on low-cost solution-grown OSSCs are here shown to operate at room temperature, providing a stable linear response with increasing dose rate in atmosphere and in radiation-hard environment. The intrinsic conversion of ionizing radiation within the crystals allowed one to fabricate all-organic optically transparent devices, indicating OSSCs as very promising candidates for a novel generation of low-cost, room temperature radiation detectors

Abstract
We report on the use of organic semiconducting single crystals (OSSCs) as direct ionizing radiation detectors that directly convert the X-ray photons into an electrical signal, thanks to their stability, good transport properties and large interaction volume. X-ray detectors, based on low-cost solution-grown OSSCs are here shown to operate at room temperature, providing a stable linear response with increasing dose rate in atmosphere and in radiation-hard environment. The intrinsic conversion of ionizing radiation within the crystals allowed one to fabricate all-organic optically transparent devices, indicating OSSCs as very promising candidates for a novel generation of low-cost, room temperature radiation detectorsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
