2019年6月13日 · Herein, we demonstrate the structural identification of Zn-N 2 active sites with both experimental/theoretical X-ray absorption near edge structure (XANES) and extended X-ray absorption fine...

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.

Recently, we have reproduced the active site of carboxypeptidase A through the synthesis and characterization of bisformatobis (2-isopropylimidazole)zinc (II) [13] and bis...

The characteristic FT-IR peaks of ZnO nanoparticles show shifts to lower wave numbers in all composites. These observed effects may be due to conjugation and some chemical interactions between...

Structural, morphological, FTIR, optical and photoluminescence (PL) measurements of Zn 1-x RE x O nanoparticles with RE = Y, La and x (0.00 ≤ x ≤ 0.20) are reported. The wurtzite structure is conrmed for all samples and the lattice parameters, Zn–O

2013年2月15日 · Cu doped ZnS thin films with crystal size below 3 nm were successfully synthesised. Substitution of Cu 2+ into Zn S lattice was confirmed by FTIR and photoluminescence. It is a great candidate for the optoelectronic devices. 1. Introduction. ZnS is an important semiconductor with direct band gap and high refractive index.

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 ...

2016年10月21日 · Fourier transform infrared (FTIR) measurements were carried out on thin films and bulk single crystals of ZnO over a wide temperature range to study the free-carrier and multi-phonon infrared absorptions and the effects of hydrogen incorporation on these properties.

2013年4月1日 · In this work, zinc sulfide (ZnS) nanoparticles were synthesized through an environmentally and economically friendly method using the fungus Fusarium oxysporum. The ZnS nanoparticles were characterized using UV–visible spectroscopy, Fourier transform infrared spectroscopy (FTIR), X-ray diffraction (XRD), and Fluorescence spectroscopy.

2016年10月21日 · 在很宽的温度范围内，对ZnO的薄膜和块状单晶进行了傅里叶变换红外（FTIR）测量，以研究自由载流子和多声子红外吸收以及氢掺入对这些性质的影响。 使用原子层沉积（ALD）和溶胶-凝胶法将铝掺杂的ZnO薄膜沉积在石英基板上。 霍尔效应测量表明，ALD膜的电阻率为 ρ = 1.11×10 -3Ωcm ，比溶胶-凝胶膜低三个数量级（ ρ = 1.25Ωcm）。 该结果与其在室温下获得的FTIR光谱所揭示的自由载流子吸收的显着差异一致。 通过将温度降低至80 K，将 …
