Nanocrystalline lead halide perovskites to boost time-of-flight performance of medical imaging detectors

Popis výsledku v původním jazyce

In this work, thin films of CsPbBr3 on top of BGO, LYSO:Ce, and GAGG:Ce,Mg wafers were fabricated to test their impact on the single crystal scintillator time resolution under soft X-rays excitation (about 10 keV). It was demonstrated that the CsPbBr3 layer significantly improves the overall time resolution in all cases, achieving up to ten-fold improvement with BGO and GAGG:Ce,Mg. Under 511 keV γ-rays, a proof-of-concept of the heterostructure design for TOF-PET using CsPbBr3 thin film deposited on GAGG:Ce,Mg bulk crystal was successfully tested. Shared events depositing energy in both materials were identified, resulting in more than twofold improved coincidence time resolution: 118±4 ps FWHM compared to the 272±8 ps of solely GAGG:Ce,Mg.n
