Meanwhile, the inserted transition layer facilitates hole injection and helps reduce electron leakage, leading to a peak external quantum efficiency of 23%.Similar content being viewed by others Solution-processed green and blue quantum-dot light-emitting diodes with eliminated charge leakage Article ...
The XRD patterns were recorded on a Rigaku SmartLab 9 kW Advance diffractometer with Cu Kα radiation (λ = 1.5418 Å). XPS spectra were collected on a Thermo Scientific Nexsa X-ray photoelectron spectroscopy using Al Kα radiation with C 1s (284.6 eV) as a reference. ...
XRD analysis was performed on Al samples cyclic pressed through ECAP using route A. Some conclusions drawn from the monitoring of dislocation density, r.m.s microstrain and effective domain size are as follows.1. Repetitive ECA pressings distort the symmetric profile of XRD peaks and to broaden...
Electrochemical nitrate reduction reaction offers a sustainable and efficient pathway for ammonia synthesis. Maintaining satisfactory Faradaic efficiency for long-term nitrate reduction under ampere-level current density remains challenging due to the in
Fig. 1(b) shows the XRD patterns of powders sintered at temperatures higher than 400 °C. Both pristine and Cl-doped nanoparticles sintered, exhibiting a hexagonal ZnO phase with a wurtzite structure (Gautam et al., 2016). The various reflection peaks observed at 2θ angle of 31.76° (010...
The amorphous structures of Al–Ni–Pr alloys with different compositions have been studied by X-ray diffraction (XRD). A distinct prepeak which characteri... J Zhou,X Bian,W Wang - 《Materials Letters》 被引量: 46发表: 2004年 Synthesis, characterization, and investigation of optical and ma...
XRD diffractograms which clearly depict the presence of crystallinity in the material, along with indexing of all the prominent peaks for (a) yttrium phosphate (YP); (b) dysprosium doped yttrium phosphate (DyYP). 3.4. Energy Dispersive X-Ray Analysis (EDAX) To study the elemental composition...
The intense main peak (white line) at 18023.0 eV is assigned to the dipole-allowed 1s-5p transitions, which is consistent with the values reported for the Zr-based carboxylate MOFs, (e.g., UiO-66) [47]. The weak pre-edge feature observed at 18003.0 eV corresponds to the dipole-...
