Embodiment Construction
[0052] The present invention will be further explained below in conjunction with the drawings.
[0053] The detector of the present invention uses an X-ray tube as the emission source, and emits broad-spectrum multicolor X-ray photons under the working condition of a fixed anode voltage. Such as figure 1 , The present invention uses MAPbX 3 The perovskite single crystal serves as the active material layer 1 for X-ray photon absorption of the detector. At MAPbX 3 In the perovskite material, X is Br, Cl or I. Thanks to MAPbX 3 Perovskite materials contain heavy elements such as Pb, Br, Cl, and I, so they can efficiently absorb X-ray photon energy and convert it directly into electron-hole pairs. In addition, MAPbX 3 Perovskite active materials have good carrier transport characteristics, such as carrier mobility, carrier lifetime and diffusion length, etc., so the photogenerated carriers generated after absorbing X-ray photons can be efficiently received, thereby Obtain higher d...
