Abstract: The present disclosure 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.
