Aqueous-solution synthesis is used to synthesize oriented ZnO nanorods on a ZnO thin film prepared by pulsed-laser deposition. The synthesis processes have been adapted to TEM-ready sapphire substrates to enable simultaneous crystallographic, microchemical and high-resolution studies in the TEM.

2024年11月19日 · The microstructure, morphology, and structural quality of ZnO nanowires grown by a vapor–solid (VS) mechanism and by oxidation during Joule heating of Zn wires by a current are compared using high-resolution transmission electron microscopy (TEM) and …

Transmission electron microscopy (TEM) images of ZnO materials synthesized through (a,d) the polyol method (ZnO-P-60), (b,e) the precipitation with carbonates...

2014年12月1日 · The synthesized ZnO nanocrystals were characterized by Fourier transform infrared (FTIR) spectroscopy, powder X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and selected area electron diffraction (SAED).

We develop scanning transmission electron microscopy–cathodoluminescence (STEM-CL) measurements, allowing the structure and cathodoluminescence (CL) of single ZnO nanowires to be mapped at high resolution.

5 天之前 · The XRD pattern and TEM image of the prepared ZnO are displayed in Fig. S2, respectively. The observed XRD pattern closely matches the standard diffraction pattern of ZnO, and the TEM image shows a rod-like morphology. These results collectively indicate the successful preparation of ZnO rods. Then the ZnO supported Pt catalyst was prepared via ...

3 天之前 · This study reports the synthesis of a novel ZnO nanostructure with a flower petal morphology using surfactant-assisted and sonochemical techniques. The ultrasonic treatment of precursors enabled the self-assembly of ZnO nanoparticles into highly porous, interconnected structures. Structural characterization via powder X-ray diffraction confirmed the presence of the wurtzite ZnO phase with ...

3 天之前 · This manuscript provides a comprehensive review of Zinc Oxide (ZnO) thin-film by various deposition techniques, primarily focusing on Chemical Bath Deposition (CBD), Spin Coating, Spray Pyrolysis, Thermal Evaporation, and Chemical Vapor Deposition (CVD) in the methodology section. This study is novel in its approach to systematically compare these widely used techniques alongside emerging and ...

5 天之前 · A maximum power density of 384.8 μW/cm 3 was obtained at R L = 10 4 kΩ, with a maximum V out = 19.9 V for ZnO@C nanorod-incorporated PVDF samples. The results demonstrate that ZnO@C nanorods exhibit superior voltage output due to their larger surface-to-volume ratio, leading to enhanced interaction with PVDF chains compared to nanoparticles.

2024年9月25日 · ZnO粉末的透射电镜选区电子衍射（SAED）分析 是一种通过透射电子显微镜（Transmission Electron Microscope, TEM）来分析ZnO（氧化锌）粉末的晶体结构和微观性质的技术。选区电子衍射（Selected Area Electron Diffraction, SAED）是一种常用的衍射方法，能够揭示晶体的对称性 ...
