2017年9月6日 · In situ XRD data on decomposition of intermediate DMF-based phases. Figure 5. Crystal structures of DMSO intermediate phases. 6. The Journal of Physical Chemistry C Article.

2021年1月1日 · Accordingly, the content of DMF was determined to be 6 μL for the following study of DMF film. However, in XRD diffraction patterns in Fig. 1 a, several unidentified peaks at 21.33°, 25.46°, 26.56°, 30.22°, 38.56° and 42.64° was observed, which may relate to the non-photovoltaic phase in perovskite film and impedes device performance.

25 mL DMF/0mL H 2O 时(S3)，结晶度和衍射峰比12.5 mL DMF/12.5mL H 2O 时的低。说明在12.5 mL DMF/12.5mL H 2O 的比例下 制备出的ZnOHF结晶度更加良好。因此通过调节DMF 的用量，可以制备出结晶良好的ZnOHF。 Figure 1. The XRD pattern of DMF products prepared with different contents at 1 mmol NH 4BF 4 图1.

2020年9月27日 · Figure 4b displays the x-ray diffraction (XRD) patterns of FAPbI 3 perovskite films prepared from DMF/NMP precursor solution containing 30 mol% MACl and subsequently annealed at 150 °C for 10 min. Two strong peaks at 14.3° and 28.6° are observed which are assigned to the (001) and (002) crystal planes of α-FAPbI3, respectively.

(a) XRD patterns of pure PbBr 2 or complex formed in different solvents. The data are obtained by sequentially dissolving PbBr 2 into the DMF/DMSO solvent, evaporating the solvent, and measuring ...

The latter solvent allowed us to obtain other DMF-free MOFs, such as ZIF-8 [28], NiFe MOF [29] and UiO-66 [30]. The obtained MSA solid exhibited an XRD pattern consistent with that simulated from ...

2024年6月1日 · X-ray diffraction (XRD) measurements were carried out to examine the phase purity of PQDs prepared via the pristine (DMF based) method and GVL-based room-temperature method as shown in Fig. 1 (a). The diffraction patterns of colloidal MAPbI 3 quantum dots synthesized via both routes matched with the standard pattern of the tetragonal MAPbI 3 ...

n,n-二甲基甲酰胺 (dmf) 的结构是在 25 °c 下使用 θ-θ 型 x 射线衍射仪通过 x 射线衍射确定的。强度降低的最小二乘分析结果表明，dmf 分子在液态下具有几乎平面的骨架结构。dmf 分子内的分子内结构参数测定如下：c=o；1.24 a，n-c(cho)；1.35 a，和 n–c(ch3)；1.45 a。

2022年11月13日 · Although the solution (DMSO/DMF) strategy has been adopted to promote the growth of crystalline perovskite thin films, ... The PbI 2-DMSO-assisted MAPbI 3 wafer shows higher XRD intensity for the (110) and (220) peaks than the conventional wafer suggesting better crystallinity in line with the SEM images. The steady-state photoluminescence ...

1 天前 · This study investigates the synthesis of gold nanoparticle (Au NP)–doped carbon nanofibers (CNFs) via laser ablation, followed by dispersion in dimethylformamide (DMF), with controlled doping achieved by varying the number of laser pulses. Structural and morphological characterizations were conducted using field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM ...
