Metal halide salts have attracted widespread attention because of their good physical and chemical properties. In this study, lead‐free copper halide salt CsCuCl3 single crystals and photodetectors were prepared. According to the single crystal diffraction data, the CsCuCl3 single crystal has a hexagonal structure with P 6522 (179) space group (7.2399 × 7.2399 × 18.3096 Å, 90.000 × 90.000 × 120.000). The crystal structure along the z ‐axis is a double‐stranded helix structure. To the best of our knowledge, this is the first study on CsCuCl3 for optoelectronic applications. The CsCuCl3 photodetector exhibits high light response, sensitivity, and selectivity under 369 nm ultraviolet light and invalid response for visible light (511 nm). The device based on CsCuCl3 is highly selective for ultraviolet light (2.43 µA/mW) and feature high anti‐interference of visible light (0.0119 µA/mW). The device has the strongest selectivity at 369 nm light, which is 200 times higher than that at 511 nm. The results will be of interest for applications in photodetectors, LEDs, devices, and metal halide salts.

全无机卤化铜盐CsCuCl3的合成,晶体结构和光电响应
金属卤化物盐由于其良好的物理和化学性质而引起了广泛的关注。在这项研究中,制备了无铅卤化铜盐CsCuCl 3单晶和光电探测器。根据单晶衍射数据,CsCuCl 3单晶具有六边形结构,具有P 6 5 22(179)空间群(7.2399×7.2399×18.3096Å,90.000×90.000×120.000)。沿z轴的晶体结构是双链螺旋结构。据我们所知,这是用于光电应用的CsCuCl 3的首次研究。氯化铯3光电探测器在369 nm紫外光下显示出高光响应,灵敏度和选择性,而对可见光(511 nm)则显示无效响应。基于CsCuCl 3的设备对紫外线(2.43 µA / mW)具有高度选择性,并具有对可见光(0.0119 µA / mW)的高抗干扰性。该器件在369 nm的光下具有最强的选择性,是511 nm的光的200倍。该结果对于光电探测器,LED,设备和金属卤化物盐的应用将是令人感兴趣的。
