摘　　要：同步辐射X射线吸收谱(XAS)/衍射(XRD)联用装置可同时表征物质的短程/长程序结构.为推进联用装置的进展,本文研制了多功能的原位池,构建温度、压力和气氛等多种原位样品环境,应用于催化反应机理、功能材料生长机制以及其稳定性等方面的研究.进一步地,通过外部触发实现X射线吸收精细结构(XAFS)/XRD数据采集与原位样品环境控制的同步.该装置成功应用于原位跟踪纳米MAPbBr_(3)钙钛矿薄膜在热降解过程中的结构演变,验证了该联用装置的可行性.同时,这种集成多功能原位样品池的联用装置也拓展了其在多维度表征方面的能力,将应用于更广泛的学科领域.The synchrotron X-ray absorption spectroscopy(XAS)/diffraction(XRD)combined device can simultaneously characterize the short-and long-range-ordered structures of substances.To promote the development of the combined device,versatile in-situ cells are developed,which provides a variety of in-situ sample environments such as temperature,pressure and atmosphere for the study of catalytic reaction mechanism,functional material growth mechanism and its stability.Furthermore,the synchronization of X-ray absorption fine structure(XAFS)/XRD data acquisition and sample environment control is achieved through an external trigger.The device is successfully applied to track the structure evolution of nano-MAPbBr_(3) perovskite films with temperature changes,which verifies the feasibility of the combined device.At the same time,the integrated versatile in-situ sample cells of the combined device also expand its ability in multidimensional characterization,and will be applied to a wider range of disciplines.
