ZnO NPs were synthesized by the wet chemical method and characterized by powder X-ray diffraction (PXRD), Fourier-transform infrared (FTIR) spectroscopy, ultraviolet–visible (UV–vis ...

FTIR spectrum of pure ZnO lm illustrates characteristic peak of ZnO at 482 cm − 1 and 555 cm − 1 , which were attributed to the Zn-O stretching vibrations (Fig. 1c) [32].

2005年8月1日 · In this letter, we use FTIR spectroscopy to investigate the LVMs of polycrystalline nitrogen-doped ZnO:N thin films. These data are interpreted through reference to existing literature on experimental and theoretical studies. We also include data on undoped polycrystalline ZnO thin films for comparison. 2. Experimental procedure.

Transform-Infra Red Spectroscopy (FT-IR): FT-IR studies were performed to verify the bond structure and identification of associated functional groups of as-synthesized...

2017年2月1日 · ZnO nanofibers were fabricated successfully by the electrospinning method using zinc acetate and PVA. FTIR and XRD studies carried out after calcinations, confirmed the formation of ZnO nanofibers by the appearance of a band at 472 cm −1, and characteristic ZnO pattern (i.e. peaks at ∼31.820, 34.331, 36.496, 47.569 and 57.168 2 θ degree ...

In this work, a simple and cheap method to prepare nanoporous ZnO using zinc nitrate, ethanol and triethanolamine (TEA) is reported. The as-prepared sample was calcined at 300 °C, 400 °C and 500 °C and studied with their structural and optical properties.

2020年2月28日 · Green synthesis of nanoparticles using plant extract is gaining importance as an alternative to conventional chemical and physical method of synthesis, because of its simplicity and environmental friendliness. In this research we synthesized Zinc oxide nanoparticle (ZnO.NPs) using plant extracts and deposited using spin- coating technique.

2022年11月21日 · Zinc oxide nanoparticles (NPs) are synthesized by the sol–gel method for optoelectronics, photonic, and medical applications. The as-synthesized NPs are irradiated with lasers with wavelengths of...

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 ...
