The metal‐to﹍igand charge transfer that was also detected in the two cases of ZnO nanoplatelets modified with the ruthenium (II) complexes caused significant alteration of the Raman spectrum and consequent changes of the optical properties. Various forms of ruthenium (II) complexes were used in...
Figure 4c shows the Raman spectrum of ZC0, which includes four characteristic peaks of the wurtzite ZnO at 326, 412, 435, and 577 cm−1, corresponding to the E2high–E2low, E1TO, E2high, and A1LO modes, respectively2. E2high is related to the oxygen in Zn–O in the wurtzite ZnO...
Figure5represents the FT-IR spectra for three distinct materials: thermal reduced graphene oxide (TRGO), pure (ZnO), and the resulting TRGO/ZnO nanocomposite. In Fig.5(a), the FT-IR spectrum of TRGO is presented, offering insights into the sample’s functional groups. Graphene oxides are kn...
Many experimental techniques were used to investigate the properties of AZO thin films such as X-ray diffraction, AFM, SEM, Raman, four points, UV–Vis–Near IR spectroscopy, and noise spectroscopy. AZO film is a particularly attractive transparent conductive oxide (TCO) because of its excellent...

a theoretical interpretation of the second-orderRaman spectrum of cubic zinc sulphide [ZnS(C)], in terms of phonons at T, X, L, and Wcritical points is presented. The set of phonon values that satisfactorily explains theobserved Raman peaks are consistent with both the neutron data and a ...
Keywords: zinc oxide nanoparticles; synthesis; physicochemical characteristics; three-dimensional structure; biomedical application 1. Introduction Metal-based drugs, generally including inorganic nanomaterials, have been studied as a next-generation nanomedicine [1,2]. Some of these dr...
(A and B) XRD patterns (A) and Raman spectra (B) of the S100, S1100, and S1200. (C and D) XPS spectra (C) and Zn content (D) of the S1100 at the depths of 2, 5, 10, and 20 nm from the surface. (E) Zn 2p spectrum of the S1100 at the depth of 20 nm. (F) Surfac...
This technique was used to prepare highly ordered and uniform nano-crystalline sensor surfaces on polyethylene terephthalate (PET) using 0.5%, 1% and 5% concentrations of zinc oxide nano-crystal suspensions. Impedance spectroscopy was employed to interrogate the sensor surfaces and confirmed high ...
Raman spectroscopy of ZnO in the range of 100–700 cm−1. Full size image Zeta potential Zinc oxide was investigated in terms of its colloidal stability in a fluid medium, which is one of the determinants of its potential applications as a nanofluid. The stability of the particles was eval...
