Nanocrystalline Lead Halide Perovskites to Boost Time‐of‐Flight Performance of Medical Imaging Detectors

Fiammetta Pagano,
Jan Král,
Kateřina Děcká
et al.

Abstract: Time‐of‐flight (TOF) technique, traditionally used in high energy physics (HEP) and positron emission tomography (PET), is now being explored for lower energy applications like computed tomography (CT). Regardless of the application, pushing the current boundaries in time resolution calls for novel technologies and materials exhibiting ultra‐fast time response. Semiconductor nanocrystals like cesium lead halide perovskites (CsPbBr3), benefiting from quantum confinement effects, feature ultra‐fast decay and, wh… Show more

“…For LHPs, this approach was first attempted by depositing a thin film of CsPbBr 3 PNCs on a scintillating wafer of LYSO:Ce and GGAG:Ce, resulting in the characteristic RL decay profile shown in Figure a,b. More recently, a similar approach has been demonstrated by Pagano et al, who obtained a 10-fold improvement of the detector time resolution by casting μm-thick CsPbBr 3 PNCs films onto GAGG:Ce, Mn, BGO, and LYSO:Ce crystals. Crucially, though, the observed luminescence enhancement of LHPs observed by Děcká et al was largely a PL contribution following the optical excitation by the scintillation light of the underlying scintillator crystal instead of direct RL by the PNCs.…”
