2023年2月1日 · Amorphous Li 3 BO 3 nanoparticles were synthesized by induction thermal plasma for the first time. Formation mechanism of amorphous Li 3 BO 3 was investigated basing thermodynamic analysis. Amorphous degree is affected by temperature distribution and chemical composition of product.

XPS 谱图解读. 当将硼注入硅中时，明显的 Si2s 等离子激元能量损失峰会对 B1s 峰造成强烈干扰。 检测硅中的低浓度硼时会有一定的挑战。 硅中硼元素检出限为每立方厘米7x10 20 个原子。 实际检测限取决于注入深度。（表面更容易检测到。

大量TiO2 的XPS 测试表明,TiO2 中Ti2p峰形为 对称峰,但存在CK 跃迁效应。 可以解释Ti4+为抗磁(自旋为0 ),无终态效应-谱峰分裂。 出现纯Ti 峰Ti2p3/2 543.1eV同时背景提升,是纯Ti本身出现背景提升还是覆盖层出现的提升?对照Ti-onSi ,发现是由于本身背景提升,源于金属Ti的多电子损失或非弹性散射。 如何处理该背景,尤其在TiO2+Ti(混相)中处理数据。 表明纯Ti 被覆盖在TiO2薄膜下。 出射信号 光电子Ti2p3 受到TiO2薄膜散射。 通常采用两种 技术处理此类问题。 ~456eV 处添 …

The properties of B-carbon nanomaterial were studied using X-ray photoelectron spectroscopy (XPS), high-resolution transmission electron microscopy (HRTEM), Raman spectroscopy, and adsorption ...

2022年7月1日 · A series of novel red-emitting BaLiZn 3 (BO 3) 3:Eu 3+ phosphors were synthesized through the high temperature solid state reaction method. The phase composition, crystal structure, morphology and photoluminescence property of the BaLiZn 3 (BO 3) 3:Eu 3+ samples were systematically investigated.

shows the XPS spectrum of B 1s for the TC0/ and TC4/CBN composites sintered at 950 °C for 1 h. The characteristic peaks of [BO4], [BO3], and the N-B bond were observed at 192.6, 191.9 [36], and...

2014年8月29日 · Here, we present the first results of an in situ high-pressure (up to 2.0 GPa) 11 B NMR spectroscopic study using this probe, in combination with ab initio calculations that directly demonstrate the nature of the transition state for BO 3 → BO 4 conversion in a commercial borosilicate glass of Corning code 7059 (13) at ambient temperature.

2007年9月13日 · The XPS examination of GdCa 4 O (BO 3) 3 revealed that the chemical composition of the crystals grown by the Czochralski method using of the sol–gel GdCOB nanopowder as a starting material have the stoichiometric composition and the smallest carbon contamination in comparison with crystals grown from oxides.

XPS, 全称为X-ray Photoelectron Spectroscopy（X射线光电子能谱）, 早期也被称为ESCA (Electron Spectroscopy for Chemical Analysis)，是一种使用电子谱仪测量X-射线光子辐照时样品表面所发射出的光电子和俄歇电子能量分布的方法。 XPS可用于定性分析以及半定量分析, 一般从XPS图谱的峰位和峰形获得样品表面元素成分、化学态和分子结构等信息，从峰强 可获得样品表面元素含量或浓度。 XPS测表面还是体相？ XPS是一种典型的表面分析手段。其根本原因在 …

在XPS谱图上，通常能够明显出现的是 自旋-轨道偶合 能级分裂谱线。这类分裂谱线主要有：p轨道的p3/2 p1/2，d轨道的 d3/2 d5/2和 f 轨道的 f5/2 f7/2，其能量分裂距离依元素不同而不同。
