Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

Abstract 2D hybrid perovskites are a novel and promising class of semiconductors for the realization of direct fast neutron detectors because they combine excellent transport properties with a large organic cation, rich in low‐Z elements, which strongly interacts with fast neutrons. Here, this study presents the employment of PEA 2 PbBr 4 (PEA = C 6 H 5 C 2 H 4 NH 3 + ) thin films for the direct detection of fast neutrons. By tuning the perovskite deposition process, it achieves a stable and reproducible response capable to monitor in real‐time the flux of fast neutrons (energy = [1–4] MeV; beam flux = [0.4–3] · 10 5 n s −1 cm −2 ) by providing an output electrical signal proportional to the radiation field intensity. Finally, the employment of a thin film‐based device boosts the discrimination capability of this technology and offers the possibility to realize a flexible and easy‐scalable detecting system very appealing for the development of wearable personal dosimeters.

Abstract

Abstract 2D hybrid perovskites are a novel and promising class of semiconductors for the realization of direct fast neutron detectors because they combine excellent transport properties with a large organic cation, rich in low‐Z elements, which strongly interacts with fast neutrons. Here, this study presents the employment of PEA 2 PbBr 4 (PEA = C 6 H 5 C 2 H 4 NH 3 + ) thin films for the direct detection of fast neutrons. By tuning the perovskite deposition process, it achieves a stable and reproducible response capable to monitor in real‐time the flux of fast neutrons (energy = [1–4] MeV; beam flux = [0.4–3] · 10 5 n s −1 cm −2 ) by providing an output electrical signal proportional to the radiation field intensity. Finally, the employment of a thin film‐based device boosts the discrimination capability of this technology and offers the possibility to realize a flexible and easy‐scalable detecting system very appealing for the development of wearable personal dosimeters.
