The atomic pair distribution function (PDF) technique is a powerful approach to gain quantitative insight into the structure of materials where the structural coherence extends only over a few nanometres. In this paper, I focus on PDF from synchrotron X-rays and describe what is the PDF and where it came from, as well as key moments on the journey that have contributed to its enormous recent growth and expanding impact in materials science today. Synchrotron X-ray sources played a starring role in this story. This article is part of the theme issue 'Fifty years of synchrotron science: achievements and opportunities'.
原子对分布函数(PDF)技术是一种强大的方法,可用于深入定量了解结构相干性仅延伸至几纳米的材料结构。在本文中,我将重点介绍同步加速器X射线的PDF,并描述什么是PDF及其来源,以及在其近期取得巨大发展并在当今材料科学中产生日益扩大影响的历程中的关键节点。同步加速器X射线源在这个故事中扮演了主角。本文是主题为“同步加速器科学五十年:成就与机遇”的一部分。
