Lead sulfide (PbS) is an important binary IV – VI semiconductor material with a narrow direct optical energy gap (0.41 eV at 300 K) and relatively large Bohr excitation...

2013年10月5日 · In the X-ray diffraction (XRD) patterns of as-prepared PbS-1, PbS-2, PbS-3, and PbS-4 films (Fig. 1), we observe reflections from only cubic (space group Fm 3 ¯ m) lead …

2015年8月1日 · The structure and phase of the PbS nanoparticles were characterized by X-ray diffraction (XRD). XRD studies reveal that as-synthesized PbS nanoparticles are in single …

2022年1月1日 · The growth of PbS film occurs either by ion-by-ion condensation of Pb 2+ and S 2− ions on the substrate surface or by the adsorption of colloidal particles of PbS. The XRD …

Powder X-ray diffraction patterns (p-XRD) of the PbS nanoparticles are indexed to face-centered cubic phase of PbS.

2023年7月4日 · UV–Vis spectroscopy, X-ray diffraction (XRD), TEM, FTIR, and photoluminescence measurement were used to examine the optic, structural, as well as …

通过 X 射线衍射 (XRD)、带 EDX 的扫描电子显微镜 SEM 和热重分析法对合成的纳米颗粒 PbS 进行分析和确认。 使用 XRD、UV-Vis、拉曼、带有 EDX 的 SEM、原子力显微镜 AFM 和霍尔 …

2016年6月2日 · The X-ray diffraction (XRD) patterns of as-deposited PbS and PbSe thin films are shown in Fig. 2. The broad peaks are related to the small crystallites due to nanostructure. …

细菌 PbS 的 X 射线衍射（XRD）图显示出清晰的衍射峰。 多晶PbS各晶面衍射角的实验数据与理论数据吻合良好。 同步加速器 XRD 测量显示没有结晶杂质衍生的峰。 因此，细菌生物矿化 …

将PBS（室温下pH 7.5）或与海藻糖（5％w / v）或甘露醇（1％w / v）一起冷冻，并用低温差示扫描量热法（DSC），X射线衍射法（XRD）表征）和pH测量。冷冻干燥的冻干物通过XRD表征。
