Bright and fast scintillation of organolead perovskite MAPbBr3 at low temperatures
Scintillators detect ionising radiation by converting energy deposited in them to a proportional number of photons. They are omnipresent in large-scale technical applications around us. Here, we report excellent scintillation properties of perovskites at low temperatures providing the potential for a new generation of cryogenic scintillators. One intriguing option would be replacing current medical scintillation detectors with cryogenic perovskites that could achieve higher imaging resolutions, for example for diagnosing early-stage brain cancer.
