摘　　要：为了解决铅基有机-无机杂化材料的不稳定性和铅元素毒性对其进一步发展和商业化应用的限制,采用水热法利用三价阳离子Sb^(3+)设计制备了一种新型无铅杂化材料(C_(6)H_(14)N)_(3)[Sb_(3)I_(12)].分别通过单晶X射线衍射、粉末X射线衍射、UV-3600紫外-可见-近红外光谱仪、数字源表和数字示波器等对其晶体结构和光电性能等进行表征.实验结果表明:(C_(6)H_(14)N)_(3)[Sb_(3)I_(12)]为典型的零维结构,相比于锑基化合物SbI_(3)和Cs_(3)Sb_(2)I_(9)具有更小的光学带隙,且在375 nm激光下表现出明显的光电响应,与传统无机材料的光电探测器相比具有更快的响应速度.In order to solve the instability of lead-based organic-inorganic hybrid materials and the limitations of lead element toxicity on their further development and commercial application,a new type of lead-free hybrid material(C_(6)H_(14)N)_(3)[Sb_(3)I_(12)]was designed and prepared by hydrothermal method using trivalent cation Sb^(3+).The crystal structure and photoelectric properties were characterized by single crystal X-ray diffraction,powder X-ray diffraction,UV-3600 ultraviolet-visible-near infrared spectrometer,digital source meter and digital oscilloscope,etc.The experimental results show that(C_(6)H_(14)N)_(3)[Sb_(3)I_(12)]has a typical zero-dimensional structure and smaller optical band gap compared with the reported antimonyl compounds SbI_(3) and Cs_(3)Sb_(2)I_(9).And it shows obvious photoelectric response under 375 nm laser,and has faster response speed compared with the photodetectors of traditional inorganic materials.
