| 2 | 基于材料调控的直接转换型铅卤钙钛矿X射线探测器研究进展显示文摘X射线探测在诸如医学成像、特定晶体结构测定、射电天文学等领域有着非常重要的作用。而传统的用于X射线探测领域的材料如硅、锑化镉等存在制备工艺复杂、成本高、X射线探测灵敏度低等缺点,严重制约了X射线探测领域的发展。近年来,铅卤钙钛矿材料作为备受关注的热点材料,因其具备较大的原子序数、高吸收系数等优点,在X射线探测领域表现出非常优异的性能。而钙钛矿材料体系是一个大家族,不同组分的钙钛矿材料各有其优缺点,即使是同一组分的钙钛矿,根据其结晶性等参数的不同,性能表现也各不相同。本文从钙钛矿材料调控的角度出发,综述了近些年来直接转换型钙钛矿X射线探测器取得的成就,并对未来钙钛矿X射线探测领域的发展趋势做出了展望。 | 胡刚舰 陈琦 魏薇 孙仔成 姚梦楠 沈亮 | 2023 | 发光学报2023，44，5： | 2 |
| 3 | 钙钛矿单晶X射线探测器:未来可穿戴电子器件的B位工程显示文摘卤化铅基钙钛矿单晶(SC)X射线探测器由于其强大的阻挡能力和高载流子传输效率而受到广泛关注。然而,铅基钙钛矿在可穿戴电子产品中的应用受到其毒性的限制。ABX_(3)杂化钙钛矿具有多种结构,通过B位点工程将光电子特性和环境友好处理相结合。在这篇展望中,我们总结了钙钛矿SC X射线探测器的最新进展,提供了从铅基到无铅再到无金属的B位工程概述。随后,提出了未来钙钛矿可穿戴电子器件的前景。我们希望这篇展望将为结构设计提供有益的指导,以实现高效、环保的钙钛矿可穿戴电子器件。 | 马闯 赵奎 | 2023 | 发光学报2023，44，3： | 1 |

| 5 | 氯化甲胺对甲胺铅溴钙钛矿单晶的钝化显示文摘为了减少甲胺铅溴(MAPbBr3)钙钛矿单晶的表面缺陷以提高其光电性能,采用氯化甲胺(MACl)的异丙醇溶液对机械打磨后的MAPbBr_(3)单晶进行钝化。通过扫描电子显微镜(SEM)、光致发光谱(PL)、时间分辨光致发光衰减谱(TRPL)、X射线衍射图谱(XRD)、X射线光电子能谱(XPS)和紫外光电子能谱(UPS)对MACl钝化后的MAPbBr_(3)单晶的结构与形貌进行表征和分析;采用钝化后的单晶制备光电探测器,考察MACl钝化对MAPbBr_(3)单晶的光电性能的影响。结果表明:经MACl钝化,机械打磨后的MAPbBr_(3)单晶表面重新结晶,载流子寿命增大约4.5倍,在形貌优化的同时有效减少了单晶的表面缺陷。氯离子的引入改变了单晶表面的晶格间距与能带结构,增大了单晶与电极之间的势垒,可使暗电流减少2个数量级,光暗电流比提高1个数量级,探测率提高近5倍。MACl钝化法简易高效,成本低廉,为MAPbBr_(3)钙钛矿单晶高性能光电探测器的开发应用提供了可行性方案。 | 陈航 林萍 王朋 崔灿 | 2023 | 浙江理工大学学报(自然科学版)2023，49，1： | 0 |
