Název v původním jazyce

Fine-grained Ce,Y:SrHfO3 scintillation ceramics fabricated by hot isostatic pressing

Popis výsledku v původním jazyce

In this work, Ce,Y:SrHfO3 ceramics were prepared by long-time vacuum sintering and short-time vacuum pre-sintering combined with hot isostatic pressing (HIP). The evolution of the microstructure in the process of densification was analyzed in detail, and the influence of the pre-sintering temperature on the density, microstructure and optical transparency of Ce,Y:SrHfO3 ceramics was studied. Under X-ray excitation, the Ce3+ 5d-4f emission of Ce,Y:SrHfO3 ceramics was observed at 400 nm, and the XEL integral intensity is 3.3 times higher than that of Bi4Ge3O12 (BGO) crystals. The light yield of the Ce,Y:SrHfO3 ceramics is approximately 3700 ph/MeV with the shaping time of 1 μs. Good optical quality and scintillation performance of Ce,Y:SrHfO3 ceramics may expand the application range and potential in the field of scintillation detection.
