Abstract

Yttrium aluminum garnet (YAG) is a composite crystalline material used as a substrate in various optical applications, especially high-power lasers. It is currently doped with different elements depending on the desired application. This has generated small controversies depending on the fabrication method as well as the doping content. In the present work, a high-purity YAG single crystal was characterized using x-ray photoelectron spectroscopy (XPS) technique. Exploratory spectra, high-resolution spectra for C 1s, O 1s, Y 3d, and Al 2p, and valence band (VB) spectra were acquired. The results showed the presence of yttrium and aluminum oxides with the characteristic stoichiometry of YAG. In addition, the presence of adventitious carbon was detected, without the presence of impurities.

用 X 射线光电子能谱分析钇铝石榴石

钇铝石榴石（YAG）是一种复合晶体材料，在各种光学应用，尤其是大功率激光器中用作基底。目前，根据不同的应用需求，钇铝石榴石会掺杂不同的元素。这在制造方法和掺杂含量上引起了一些争议。本研究利用 X 射线光电子能谱（XPS）技术对高纯度 YAG 单晶体进行了表征。研究人员获取了探索性光谱、C 1s、O 1s、Y 3d、Al 2p 的高分辨率光谱以及价带（VB）光谱。结果表明，钇和铝氧化物的存在具有 YAG 的特征化学计量学。此外，还检测到了不定形碳的存在，且不含杂质。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
