    • The present invention provides a convertor for X-ray radiography and its manufacturing method and an X-ray detector, wherein the surface of the scintillator facing the X-ray is covered with photonic crystals of a two-dimensional or three-dimensional spatial structure capable of reflecting the visible light facing the photonic crystals generated by the scintillator to increase the intensity of the output light of the scintillator by more than 100%, thus enhancing the image brightness and improving the image resolution, in addition to reducing to a certain extent the interference between pixels due to the ability of the photonic crystals to control the direction of the light being reflected, for example, by controlling the reflecting direction so as to be vertical to the surface of the scintillator, and the manufacturing method and material for the photonic crystals are low in cost without toxicity, enabling it to be used more widely.
    • 本发明提供一种用于X射线摄影的转换器及其制造方法和X射线检测器,其中面向X射线的闪烁体的表面被二维或三维空间结构的光子晶体覆盖, 反射由闪烁体产生的面向光子晶体的可见光,以将闪烁器的输出光的强度提高大于100%,从而增强图像亮度并提高图像分辨率,除了在一定程度上降低 由于光子晶体控制反射光的方向的像素之间的干涉,例如通过控制反射方向以垂直于闪烁体的表面,以及光子的制造方法和材料 晶体成本低,无毒性,使其可以更广泛地使用。
