Embodiment 1
[0037] The preparation method of the perovskite single crystal X-ray detector provided by the present invention comprises the following steps:
[0038] (1) Weigh 0.1109 g of FABr and 0.367 g of PbBr 2 , added to a closed glass bottle;
[0039] (2) Add 2 mL of DMF solvent to step (1), and put a magnetic stirring bar;
[0040] (3) Place the glass bottle on a magnetic stirring table and stir at room temperature for 12 h until the perovskite material is completely dissolved to obtain FAPbBr 3 Solution (perovskite single crystal growth solution);
[0041](4) Place the glass bottle on a preheated hot stage (75°C) and let it stand for 1.5 h until small orange perovskite seed crystals grow in the solution;
[0042] (5) Select a cuboid with a regular shape, square upper and lower surfaces, a small seed crystal grain with a side length of 0.1~0.2 cm and a thickness of 0.05~0.1 cm, and transfer it to the newly prepared perovskite single crystal growth solution. , and placed it on a p...
Embodiment 2
[0046] (1) Weigh 0.1109 g of FABr and 0.367 g of PbBr 2 , added to a closed glass bottle;
[0047] (2) Add 1.6 mL of DMF and 0.4 mL of GBL to step (1), and put in a magnetic stirring bar;
[0048] (3) Place the glass bottle on a magnetic stirring table and stir at room temperature for 12 h until the perovskite material is completely dissolved to obtain a perovskite single crystal growth solution;
[0049] (4) Place the glass bottle on a preheated hot stage (75°C) and let it stand for 1.5 h until small orange perovskite seed crystals grow in the solution;
[0050] (5) Select a cuboid with a regular shape, square upper and lower surfaces, a small seed crystal grain with a side length of 0.1~0.2 cm and a thickness of 0.05~0.1 cm, and transfer it to the newly prepared perovskite single crystal growth solution. , and placed it on a preheated hot stage (55 °C), with an initial temperature of 55 °C for 30 h at a rate of 0.5 °C / h, until the upper and lower surfaces of the square wer...
Embodiment 3
[0054] (1) Weigh out 0.1109 g of FABr and 0.367 g of PbBr 2 , added to a closed glass bottle;
[0055] (2) Add 1.2 mL of DMF and 0.8 mL of GBL to step (1), and put in a magnetic stirring bar;
[0056] (3) Place the glass bottle on a magnetic stirring table and stir at room temperature for 12 h until the perovskite material is completely dissolved to obtain a perovskite single crystal growth solution;
[0057] (4) Place the glass bottle on a preheated hot stage (75°C) and let it stand for 1.5 h until small orange perovskite seed crystals grow in the solution;
[0058] (5) Select a cuboid with a regular shape, square upper and lower surfaces, a small seed crystal grain with a side length of 0.1~0.2 cm and a thickness of 0.05~0.1 cm, and transfer it to the newly prepared perovskite single crystal growth solution. , and placed it on a pre-heated hot stage (55 °C), with an initial temperature of 55 °C for 30 h at a rate of 0.5 °C / h, until the upper and lower surfaces of the squar...
