【摘要】 探究了LYSO∶Ce晶体的余辉现象,以及在不同曝光时间、光照强度下,余辉计数率随时间的变化规律。同时探究了温度对晶体余辉强度的影响,发现加热晶体可以快速缩短余辉持续时间,这一发现为日常的晶体检测和应用带来一定便利。更多还原

【Abstract】 The article explored the afterglow effect of LYSO ∶ Ce scintillation crystals and the afterglow count rate changing with the time under various exposure times and light intensity.Based on that,it also explored the influence of temperature on the crystal afterglow and found that heating could shorten the afterglow,the find can bring some convenient for routine testing and application of scintillation crystals.更多还原
