Timing performance of lead halide perovskite nanoscintillators embedded in a polystyrene matrix
Original language description
In this work, we present the production, characterization, and – for the first time – time resolution measurements of CsPbBr3 nanocrystals embedded in polystyrene, using two different surface ligands (OA + OAm and DDAB) and three different filling factors of up to 10%. The samples were characterized by spectroscopic methods, namely photoand radio-luminescence as well as transmittance, while scintillation decay kinetics was measured in a time correlated single photon counting setup upon X-ray excitation. In addition, the time resolution of these materials was measured using a novel setup coupled to analog silicon photomultipliers and low energy pulsed X-ray excitation. When comparing with the state of the art inorganic(LYSO:Ce) crystal, more than twofold time resolution improvement was obtained. These first promising results represent the starting point for the optimization of CsPbBr3 nanocrystals embedded in polymer matrices and their application in fast timing detectors for TOF-CT, TOF-PET and high energy physics.n
