摘要: 近年来，钙铁石结构材料KBiFe2O5 (简写为KBFO)因其多铁特性而得到人们的关注，其带隙约为1.6 eV，成为了继室温单相多铁材料铁酸铋之后的另一类铁电光伏候选材料。本工作利用溶胶–凝胶法(sol-gel)制备了Zn掺杂的KBFO材料，研究Zn掺杂对KBFO材料的结构和物性的影响。研究结果表明，掺杂使样品的结构发生轻微的畸变，其磁学性能和光学带隙在掺杂量为5%变化最明显。本工作对进一步理解KBiFe2O5材料的带隙结构、磁性、电特性及其调控提供实验参考。
Abstract: In recent years, KBiFe2O5(KBFO) with a band gap of about 1.6eV has attracted attention due to its multiferroic properties，and has become another class of ferroelectric photovoltaic candidate materials after BiFeO3, a single-phase room-temperature multiferroic material. In this paper, Zn-doped KBFO material was prepared by sol-gel method, and the effect of Zn-doped on the structure and physical properties of KBFO material were studied. The results show that Zn-doped distorts the structure of the sample slightly, and the magnetic properties and optical band gap change most obviously when the doping amount is 5%. This work provides an experimental reference for further understanding of the band-gap structure, magnetic and electrical properties and their regulation in KBiFe2O5 materials.
