摘要：
ZnO-based scintillators are particularly well suited for use as ultrafast pulsed radiation detectors which have shown broad application prospects in various fields such as the inertial confinement fusion (ICF) diagnosis, the nuclear reaction mechanism, etc. Using the hydra thermal method, a ZnO single crystal doped with Scandium (ZnO:Sc) sample was prepared. As a new ZnO-based scintillator, the scintillation characteristics of ZnO:Sc have not been reported previously. In this paper, optical and scintillation characteristics of ZnO:Sc single crystal were studied. Also a scintillation detector based on ZnO:Sc was designed. Excited by the alpha particle, the rise time of ZnO:Sc detectors was from 162.5 to 170.7 Ps, and the fall time was from 300.4 to 328.8 ps. (C) 2014 Elsevier B.V. All rights reserved.
