| titleOfInvention | Controllable growth method of [110] crystal face of dodecahedral methylamine lead bromide perovskite single crystal and its application in X-ray detector |
| abstract | The invention discloses a controllable growth method for the [110] crystal plane of a dodecahedral-shaped methylamine lead bromide perovskite single crystal and its application in an X-ray detector, belonging to the technical field of X-ray detectors. The invention adopts the method of adjusting the non-stoichiometric ratio of feeding raw materials and simultaneously controlling the solution conditions and growth temperature, so that the growth of the perovskite single crystal plane can be effectively regulated, and the anisotropy of the single crystal is reflected. The resulting [110] planes have lower defect state density, higher resistivity and better carrier transport properties than the exposed [100] planes in the cubic shape. The sensitivity of the X-ray detector prepared by the invention under 120keV hard rays reaches 3928.3 μC/Gy air /cm 2 , which is higher than the sensitivity of the [100] crystal plane X-ray detector; and the dose rate is 8.8 μGy air /s. , compared with the CsI scintillator for medical imaging, it shows a stronger signal-to-noise ratio, which provides a basis for the design of high-performance X-ray detectors. At the same time, the detector has a simple structure and is easy to manufacture. |
