摘要

离子掺杂YAG晶体（Yb∶YAG）作为一种性能优良的激光晶体已广泛应用于高效、高功率激光领域。最新研究表明，Yb∶YAG晶体响应时间可达0.411ns，其优良的超快闪烁特性在超快脉冲辐射探测、惯性约束核聚变、空间辐射探测、核反应动力学等领域的应用引起了广泛关注，使得Yb∶YAG晶体成为超快闪烁材料研究的热点。关于Yb∶YAG的闪烁特性，文章在系统介绍Yb∶YAG作为超快闪烁晶体研究进展和发光机理的基础上，归纳总结了掺杂种类、浓度、后处理工艺、辐照、格位尺寸大小、温度等对Yb∶YAG晶体闪烁性能的影响。然后，针对Yb∶YAG目前存在的问题，给出相应的解释并提出通过离子共掺调控来改善其闪烁性能的方法。最后，对Yb∶YAG超快闪烁晶体未来的发展方向进行了展望。

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

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.
