[0021] A preparation method of an X-ray detector, comprising the following steps:
[0022] S1. Use a ball mill to grind the perovskite and MXene bulk materials, and mix the ground perovskite and MXene powder materials evenly;
[0023] S2. Put the perovskite and MXene mixed powder material into a stainless steel mold, and use a manual tablet press to continuously apply a pressure of 20Mpa for 2 minutes to press the perovskite and MXene mixed powder material into a block with regular shape and dense surface;
[0024] S3, further using a cold isostatic press to apply a pressure of 200Mpa to the block prepared in step S2 for 15 minutes, and finally obtain a perovskite / MXene composite absorbent material with a dense cross-section;
[0025] S4. Finally, thermal evaporation equipment is used to evaporate electrodes on both sides of the perovskite / MXene composite absorption material obtained in step S3 to form an X-ray detector with a metal / semiconductor / metal structure.
