    • The present approach involves a radiation detector module with increased quantum efficiency and methods of fabricating the radiation detector module. The module includes a scintillator substrate and a photodetector fabricated on the scintillator substrate. The photodetector includes an anode, active organic elements, and a cathode. The module also includes a pixel element array disposed over the photodetector. During imaging, radiation attenuated by an object to be imaged may propagate through the pixel element array and through the layers of the photodetector to be absorbed by the scintillator which in response emits optical photons. The photodetector may absorb the photons and generate charge with improved quantum efficiency, as the photons may not be obscured by the cathode or other layers of the module. Further, the module may include reflective materials in the cathode and at the pixel element array to direct optical photons towards the active organic elements.
    • 本方法涉及具有增加的量子效率的辐射检测器模块和制造辐射探测器模块的方法。 该模块包括闪烁体基板和在闪烁体基板上制造的光电检测器。 光检测器包括阳极,有源有机元件和阴极。 模块还包括设置在光电检测器上方的像素元件阵列。 在成像期间,由待成像的物体衰减的辐射可以通过像素元件阵列传播并且通过光电检测器的层传播,以被闪烁体吸收,闪烁体响应于发射光子。 光电检测器可以吸收光子并产生具有改善的量子效率的电荷,因为光子可能不被模块的阴极或其它层遮蔽。 此外,模块可以包括在阴极和像素元件阵列处的反射材料,以将光学光子引向有源有机元件。
