英文摘要:
As an superior performance of laser crystal,Yb-doped YAG crystal has been widely used in high efficiency and power laser field. New research has shown that the response time of Yb∶ YAG can attain up to 0.411 ns. The super ultrafast scintillation property of Yb∶ YAG ultrafast scintillator has attracted broad attention in many researches such as pulsed radiation detection,inertial confinement fusion,space radiation detection and nuclear reaction kinetics. First of all,we described the research progress and ultrafast scintillation mechanism of Yb∶YAG crystal in this paper. Then,based the ultrafast scintillation mechanism above,the influences of temperature,Yb~(3+) concentration,size of cation site,high energy ray irradiation and post-treatment on ultrafast scintillation were also discussed in detail. Aiming at the existing problems of Yb∶ YAG ultrafast scintillation crystal,this paper presented corresponding explanation and the method of co-doped cation to influence the charge density distribution around so that to improve the scintillation properties. At last,we prospected the development direction of Yb∶ YAG ultrafast scintillator in the future.
