摘　　要：铋层状结构铁电体(BLSF)作为一种类钙钛矿无铅铁电压电材料,由于其在高温、高频以及非易失性铁电随机存储器等领域具有突出的综合优势,因而受到广泛关注。本文以BLSF的综合特征为基础,对其结构设计和微结构研究中存在的问题进行了详细探讨,并重点总结了近二十年来其在性能优化和薄膜制备中取得的进展。此外,本文还对一些以铁电为背景的新的研究方向做了介绍。最后提出了BLSF在未来发展中值得关注的几个重要问题。As an improtant lead-free ferroelectric/piezoelectric system, the past few decades have attracted increasing attention of bismuth layer structured-ferroelectrics （BLSF） due to its comprehensive advantages in the areas of high temperature, high frequency and ferroelectric random access memory （FRAM）. In this paper, the recent progresses on the study of this system were reviewed. Firstly, as the basic of other researches, the key issues in strucutre design and microstructure study were dicussed in detail. Then special emphasis was put on ferroelectric/ piezoelectric performance and film technology. Additionally, some new research fields that were closely related to ferroelectric were introduced. In the end, the research directions were also extracted according to the authors＇ knowledge.
