摘要

布里奇曼生长的 CsPbBr3 单晶体已显示出高分辨率的 γ 射线光谱，使其极有希望成为当前基准室温辐射探测器 Cd1-xZnxTe 的竞争对手。然而，CsPbBr3 晶体生长是一个非常缓慢的过程，由于从立方晶系到正方晶系的相变，经常会导致晶锭开裂。在本报告中，我们展示了如何在 Cs(Pb1-xSnx)(Br3-yCly)固溶体中稳定室温立方相，以克服这一问题。Cs(Pb0.75Sn0.25)(Br1.00Cl2.00)被确定为最有前途的成分，并利用布里奇曼生长法在一周左右的时间内生长为无裂纹铸锭。

Cubic halide perovskites in the Cs(Pb1−xSnx)(Br3−yCly) solid solutions for crack-free Bridgman grown single crystals

Bridgman grown CsPbBr₃ single crystals have demonstrated γ-ray spectra with a high resolution, making them a highly promising competitor for the current benchmark room-temperature radiation detector Cd_1−xZn_xTe. However, CsPbBr₃ crystal growth is a very slow process that oftentimes results in cracked ingots due to phase transitions from cubic to orthorhombic crystal systems. In this report, we demonstrate the stabilization of a room-temperature cubic phase in Cs(Pb_1−xSn_x)(Br_3−yCl_y) solid solutions to overcome this issue. Cs(Pb_0.75Sn_0.25)(Br_1.00Cl_2.00) was identified as the most promising composition and grown as a crack-free ingot using Bridgman growth in around one week.
