    • The invention relates to a method for optimizing photon management in scintillation crystals. Said method is characterized in that it includes the following steps: depositing a material (5), having a refractive index "n" approximately equal to the refractive index of a scintillation crystal (1), on one surface (2) of said scintillation crystal; structuring said material (5) via a structuring means; and creating sub-diffractive size structures (6) in said material (5) such as to enable the refractive index to be adapted between the scintillation crystal (1) and the material (5) on said surface (2) and/or create structures (6) at the diffraction limit in said material (5) in the form of a single-order blazed distribution grating by directly redirecting the photons reflected on the side surfaces (20) of said crystal toward the surface (2) of said crystal, such as to enable the time distribution to be reduced. The invention also relates to the means for structuring the material (5) and to the scintillation crystal thus optimized for photon management. The invention further relates to the use of a scintillation crystal, optimized according to the above method, in particle detection systems and/or medical imaging and/or security systems and/or for radiation-related monitoring.
    • 本发明涉及一种用于在闪烁晶体优化光子管理的方法。 所述方法的特征在于它DASS包括以下步骤:沉积材料(5),其具有的折射率的“n”大约等于一个闪烁晶体(1)的折射率,在一个表面(2)的所述闪烁晶体 ; 所述构筑材料(5)通过的结构化装置; 和创建子衍射尺寸的结构(6)所述材料(5):如,以使折射率所述闪烁晶体(1)和所述材料之间angepasst(5)在所述表面(2)和/或创建的结构 (6)在所述材料的衍射极限(5)在一单阶的形式闪耀分布光栅通过直接重定向的光子反射所述晶体的朝向表面(2)所述晶体的侧表面(20)上, :如,以使分配的时间被减少。 因此,本发明涉及的装置用于构造材料(5)和用于光子管理THUS优化闪烁晶体。 本发明还涉及到使用一个闪烁晶体,雅丁优化,以上述方法的,在粒子检测系统和/或医学成像和/或安全系统和/或辐射相关的监测。
