XPS studies and factor analysis of PbS nanocrystal-doped SiO
1999年7月1日 · PbS nanocrystal-doped SiO 2 glass thin films and a single evaporated PbS film were studied by X-ray photoelectron spectroscopy (XPS) and factor analysis (FA). The composite films contained PbS crystallites with mean dimensions as small as 1–2 nm dielectrically embedded in the SiO 2 host.

Present research work highlights the efforts to study the synchronized effect of TiO 2 and PbS on the power conversion efficiency of quantum dot sensitized solar cell (QDSSC).
铅 | Thermo Fisher Scientific - CN
铅的化学符号 Pb 来源于拉丁文 "plumbum"，原意为“液态银”。 长期接触铅会导致神经损伤、肾疾病、心血管疾病和生殖毒性。 虽然铅的有害影响早在公元前2000年就被确认，但有史以来却一直用铅来制作管道和弹药。 最近，铅被用于制作蓄电池、油漆、汽油和吸音材料，但由于健康和环境影响，这些用途正在逐步淘汰。 返回元素表. 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。
XPS-and-DFT analyses of the Pb 4f - ScienceDirect
2017年5月31日 · We used the appropriate XPS spectra of Pb-metal (Pb 0), α-PbO 2 (Pb 4+) and α-PbO (Pb 2+) XPS external standards for comparison and qualification of the Pb 4f core-levels structure of our samples. Our selection was justified by the relatively high stability of these lead compounds at normal ambient.
Optimizing Surface Chemistry of PbS Colloidal Quantum Dot for …
2020年11月27日 · Here, we present a new strategy to simultaneously eliminate the undesirable sites and efficiently passivate the surface of PbS CQD via a facile one-step process. In this process, the complex ligand comprising PbX 2 (X = I and Br) matrix and potassium triiodide (KI 3) additive was employed to optimize the surface chemistry.
