Description
Technical Field
The invention relates to the technical field of flexible direct ray detection, in particular to an application of a metal organic framework material composite matrix film as a flexible direct ray detection material.
Background
X-rays are electromagnetic waves of extremely short wavelength and large energy. X-rays have a shorter wavelength than visible light, meaning that the X-ray photon energy is tens of thousands to hundreds of thousands times greater than the photon energy of visible light. The above-mentioned special properties give X-rays many properties in addition to the general properties of visible light. Due to the characteristics of X-ray, the X-ray can be widely applied in the fields of environmental monitoring, medical diagnosis, industrial nondestructive testing, safety inspection, nuclear science and technology, astronomical observation, high-energy physics and the like shortly after being discovered. Whereas the detection of X-rays is the basis for all X-ray applications.
The detection material is the core content for realizing radiation detection. The current detectors are divided into three generations: gas detector, scintillator detector, semiconductor detector. The semiconductor detection material with the most obvious advantages is a direct detection material, ionization excitation is generated in the semiconductor by irradiation of high-energy rays, electron-hole pairs are generated in the semiconductor by charged particles, and the electron-hole pairs drift under the action of an external electric field to output signals. The detector of this generation has made up the numerous disadvantages of the former two generations of detectors such as large volume, low sensitivity, complex instrument and low detection efficiency.
Commercial semiconductor detectors are developed more mature at present, including silicon (Si) detectors, high-purity germanium (Ge) detectors, and cadmium zinc telluride (CdZnTe). But the silicon (Si) detector has a low atomic number and is only used for lower energy ray detection; the high-purity germanium (Ge) detector has small band gap and needs to be cooled and can only work at the temperature of liquid nitrogen; the cadmium zinc telluride (CdZnTe) detector needs severe growth conditions and a long period, so that the cost of the material is high.
In recent years, the emerging detector type is mainly a perovskite detector, in 2016, centimeter-level lead-bromine-methyl-ammonium perovskite single crystal (MAPbBr) is reported for the first time by Huangjinson et al, Lincoln university, England-Las, USA3) The crystal has ultra-high mobility lifetime product (1.2 × 10)-2cm2V), this work achieved low dose X-rays (0.5 μ Gy)airResponse under irradiation/s) detectiveThe sensitivity can reach 80 (mu C.Gy)air)/cm2The performance of the detector can reach the same level with commercial detectors such as Cd (Zn) Te and amorphous Se. Many researchers have also made a lot of meaningful work in the perovskite field afterwards.
The field of the detection material is mainly focused in the field of medical human body X-ray imaging, the existing detection technology is mainly a planar X-ray detection technology, and a three-dimensional image needs to be obtained by multiple angles and multiple irradiations in the diagnosis process and then is obtained by computer fitting. It has been reported that the X-ray dose to which a human body is subjected during this diagnostic procedure has significantly increased the probability that a patient will suffer from cancer. The flexible X-ray detection material can obtain images of multiple angles through single imaging, and therefore the 3D effect is achieved. The irradiated dose of the human body is reduced, thereby achieving the effect of protecting the patient. The existing flexible detection materials are mostly finished by organic crystals, the organic crystals have good chemical compatibility with a flexible substrate, can be grown and processed in a solution form, and are easy to manufacture a large-area film, but the biggest defect of the organic crystals is weaker X-ray absorption capacity. Therefore, the flexible detection material can be only used for detecting some low-energy X-rays, and the application range is extremely small.
CN201510023169.3 discloses an SEBS thermoplastic elastomer capable of detecting X-rays, an SEBS thermoplastic elastomer product and a production method thereof, wherein the SEBS thermoplastic elastomer product can be developed under an X-ray detector. CN201911001924.2 discloses a series of metal organic frameworks, pharmaceutical formulations and their use in the preparation of medicaments. The metal organic framework containing the photosensitizer needs to be matched with a part capable of absorbing X-rays and/or scintillation light for absorption of the X-rays.
Therefore, it is necessary to solve the technical problems of the radiation detector such as high rigidity, heavy weight, non-portability and complex device, and to develop more and more radiation detector materials capable of flexible imaging.

The results show that the current of the metal organic framework material composite matrix membrane is obviously improved under the irradiation of X rays with different doses, and the current is obviously changed along with the change of the X ray dose (see figure 3).
