采用改进的 Cr 2 O 3 拟合方法，对暴露于空气中的铬铅矿石 (PbCrO 4) 进行了峰拟合，增加了 Cr (VI) 态的分量。 铬是一种具有延展性的硬金属，因其抛光后的诱人光泽而闻名。 铬的名称源于希腊语中的颜色，这是因为铬可以形成多种多彩的化合物。 在1800年代，铬主要用作皮革油漆和鞣制盐的成分。 如今，85% 的铬用于金属合金，如不锈钢和阳极氧化铝。 在红宝石和绿宝石等宝石中也存在痕量的铬。 铬是一种常见的元素， 用于生产合成宝石。 返回元素表. 铬是一种具有延 …

... order to investigate the dispersity of Cr species over the LPMS-130 mesoporous silica surface, SEM imaging and EDX elemental mapping were conducted on the LPMS-130, Cr (4) X-ray...

The Basic XPS Information Section provides fundamental XPS spectra, BE values, FWHM values, BE tables, overlays of key spectra, histograms and a table of XPS parameters. The Advanced XPS Information Section is a collection of additional spectra, overlays of spectra, peak-fit advice, data collection guidance, material info,

Interpretation of XPS spectra. In the presence of high concentrations of zinc, it may be difficult to assign chromium chemistry using the Cr2p region, due to strong overlap with the Zn LMM Auger region. The secondary chromium peak, Cr3p, shows reasonably large chemical shifts and may be easier to peak fit in this situation.

The XPS Spectra section provides raw and processed survey spectra, chemical state spectra, BE values, FWHM values, and overlays of key spectra. Atom% values from surveys are based on sample, as received, and Scofield cross-sections. Atom% values are corrected for IMFP and PE. Peak-fits are guides for practical, real-world applications.

文献上Cr的XPS峰一般为+3价，+5价，+6价，但是我的峰有四个，不知道还有一个什么峰，求虫友们指教，不胜感激！ 拟合峰值分别为575.16eV,576.22eV，577eV,579.76eVQQ截图20180626101606.png 催化.

2012年6月29日 · 这是学校购买的第一台XPS，所以实验室没人做过XPS，我只是自学了点皮毛。有个问题请教一下，分析测试中心给出的结果是Cr2P scan，你提到的我只拟合了 Cr2p3/2，而没有 拟合Cr2p1/2。

2020年9月1日 · The results of X-ray photoelectron spectroscopy (XPS) study of Cr(30 Å)/[Pd(4 Å)/Gd(50 Å)/Pd(4 Å)/Fe(35 Å)] and Cr(30 Å)/[Pd(20 Å)/Gd(50 Å)/Pd(20 Å)/Fe(35 Å)] multilayered nanostructures grown with magnetron sputtering are presented.

xps 元素参照表 用于 XPS 的 Thermo Scientific™Avantage™ 数据系统的一个重要特征是拥有庞大的知识库，能提供 XPS 分析和元素表征相关的信息。 此处按元素周期表排列，给出了知识基础库。

2017年1月1日 · In this paper chromium oxide (Cr 2 O 3) thin films have been prepared onto MgO (0 0 1) substrate by thermal evaporation method at a pressure of about 1 × 10 −4 Pa. The morphology of the obtained thin films was investigated. These films show homogeneous and uniform distribution according to AFM images.
