Incorporating heteroatoms in functional materials is an invaluable approach to modulate their properties, assuming a solid solution is formed. However, thorough understanding of key structural information on the resulting solid solution, such as the local environment of cations and vacancies, remains a challenge. Solid‐state NMR (SSNMR) spectroscopy is a powerful structural characterization tool, very sensitive to the local environment. Due to the difficulty in signal acquisition and spectral interpretation, SSNMR spectroscopy is relatively less known to chemists and materials scientists. Herein, we present an introductory review to demonstrate how to use ⁸⁹Y SS NMR spectroscopy to unravel the mystery of solid solutions. In general, ⁸⁹Y chemical shift varies with different cation/vacancy arrangements in Y coordination spheres, providing ultrafine structural information in the atomic scale. As a case study and an extreme condition, the approach demonstrated in this review can be extended to other systems.

揭示固溶的奥秘：以89 Y固态NMR光谱为例的研究。

假设形成固溶体，则将杂原子掺入功能材料中是调节其性能的宝贵方法。然而，对所得到的固溶体的关键结构信息（例如阳离子和空位的局部环境）的透彻理解仍然是一个挑战。固态NMR（SSNMR）光谱是一种功能强大的结构表征工具，对本地环境非常敏感。由于信号采集和光谱解释的困难，化学家和材料科学家对SSNMR光谱的了解相对较少。在这里，我们提供一个介绍性综述，以演示如何使用⁸⁹ Y SS NMR光谱来揭示固溶体的奥秘。总的来说⁸⁹Y化学位移会随着Y配位球中不同的阳离子/空位排列而变化，从而提供原子级的超细结构信息。作为一个案例研究和一种极端情况，本综述中演示的方法可以扩展到其他系统。
