LaBr3：Ce在80 K下闪烁比和能量分辨率的改善
Improved scintillation proportionality and energy resolution of LaBr3:Ce at 80K
摘要：
利用10.5 - 100 keV的高单色同步辐射X射线，研究了掺5%Ce ~（3+）的LaBr_3晶体在80 K、295 K和450 K下的非比例性和能量分辨率随温度的变化。在降低温度时观察到比例性的改善和更好的能量分辨率。这种效应表明，LaBr 3：Ce已经出色的能量分辨率可以进一步提高。它也可能提供新的线索，以更好地理解的过程，导致非比例性的无机闪烁体响应。
英文摘要：
Using highly monochromatic synchrotron X-rays in the energy range from 10.5 keV to 100 keV the temperature dependence of nonproportionality and energy resolution of LaBr3 scintillators doped with 5% Ce3+ were studied at 80K, 295K, and 450K. Improvement of the proportionality and better energy resolution was observed on lowering the temperature. This effect suggests that the already outstanding energy resolution of LaBr3:Ce can be improved even further. It also may provide new clues to better understand the processes that cause nonproportionality of inorganic scintillator response.
