Solid‐state synthesis led to a mixed KPbF 2 Cl HP with an orthorhombic structure as determined from X‐ray diffraction and energy dispersive X‐ray spectroscopy. The high formation energy (‐0.546...

2021年2月1日 · The Pb:I:Cl ratio from XPS were: 1:4.0:0 (sample MAI + PbI 2), 1:3.9:0 (sample MAI + PbCl 2), and 1:3.9:0 (sample MAI + PbCl 2 /PbI 2). Again, this excessive iodine content is consistent with the absence of unbonded metallic lead, which confirms the …

2017年8月31日 · It is revealed that PbCl 2 can act both as a crystal structure controller for phase transition of CsPbBr 3 from orthorhombic to cubic at a relatively high content of PbCl 2, and as an interfacial modifier for boosting electron extraction rate from CsPbBr 3 to TiO 2.

XPS 光谱解读. Pb4f 区域具有明显的自旋轨道分裂峰 (Δ 金属 =4.87eV)。 铅金属 Pb4f 区域的谱峰峰形不对称。 对暴露于空气后的铅金属进行 O1s 区域分析，结果表明铅的天然氧化物中氢氧化铅的浓度较高。 基本信息说明

2001年11月1日 · A structural characterization of PbO–PbCl 2 –CdCl 2 oxychloride glasses was achieved using 207 Pb and 113 Cd nuclear magnetic resonance (NMR) and X-ray photoelectron spectroscopy (XPS). 207 Pb static NMR spectra exhibit two broad components, whose intensity change with oxygen–chlorine substitution in the glass composition.

2021年5月2日 · PbCl 2 additive engineering is an effective method to decrease the charge accumulation in devices. Herein, the influence of PbCl 2 additive on the charge transport properties of inverted planar MAPbI 3 perovskite devices is investigated by capacitance–voltage (C – V) spectroscopy.

2017年7月12日 · 为了提高薄膜质量，人们研究了平面异质结结构中的混合Sn/Pb基PSC，开发了一种改进的合成路线，以制备具有高表面覆盖度的Pb-Sn二元PVSK膜。在本研究中，将所制备的MAI，PbCl2和SnCl2在无水DMF中以一定摩尔比混合，将得到的混合溶液在80℃下搅拌过夜。

In this study, the synergistic poisoning of KCl and PbCl2 on commercial V2O5-MoO3/TiO2 SCR catalysts was investigated. Compared with KCl, PbCl2 could combine with Mo components and protect V...

2023年11月1日 · We originally adopt a two-type ligand strategy to fabricate bulk PNCs/polystyrene (PS) nanocomposites, including a new type of synthetic polymerizable ligand. The CsPbCl 3 PNCs/PS nanocomposites...

2017年3月30日 · For PbI 2 and PbCl 2 salts no traces of the former salt are observed in the MAPbBr 3 layer obtained after 10 minutes of dipping time, however, the presence of PbBr 2 has still been detected (using X-ray diffraction) when this salt has been employed.
