“…The deeper layer (bulk) reveals a smooth pattern, lacking prominent oscillations, similar to the one corresponding to pure Fe in reference data of Figure 7. The result says that the most superficial layer, deposited at 200 ∘ C, seems to be oxidized as Fe 3 O 4 (Fe(II,III) These results have a consistent behavior with previous work [36].…”

X-ray resonant Raman scattering is applied at grazing incidence conditions with the aim of discriminating and identifying chemical environment of iron in different layers of stratified materials using a low resolution energy dispersive system. The methodology allows for depth studies with nanometric resolution. Nanostratified samples of Fe oxides were studied at the Brazilian synchrotron facility (LNLS) using monochromatic radiation and an EDS setup. The measurements were carried out in grazing incident regime with incident photon energy lower than and close to the Fe-K absorption edge. The result allowed for characterizing oxide nanolayers, not observable with conventional geometries, identifying the oxidation state present in a particular depth of a sample surface with nanometric, or even subnanometric, resolution using a low-resolution system.

Cadmium oxide (CdO) thin films were grown on glass substrates by chemical bath deposition (CBD) method for different deposition times using cadmium acetate as cationic precursor. The structural and optical characterization was carried out using XRD, TEM, and UV-Vis spectrophotometer measurements. Structural analyses with XRD confirmed cubic structure of the CdO. Average particle size estimated from Rietveld refinement method of XRD pattern corresponded well with TEM measurement. The optical band gap varied between 2.35 eV to 2.48 eV with deposition time and an increase in optical band gap with decreasing film thickness was observed. The AC electrical conduction behavior of the CdO film was investigated as a function of temperature as well as frequency. The conductivity measurements indicated localized conduction and hopping of carriers between localized states. The value of real part of dielectric constant was found to decrease with frequency and increase with temperature. The Nyquist plots at different temperatures showed the existence of both grains and grain boundaries contributing to conduction mechanism.

“…Iron oxide nanoparticles play a vital role in many fields of chemical, physical, and material science [3,4]. Iron oxides occur in a variety of forms, but magnetite (Fe3O4), maghemite (γ-Fe2O3), and hematite (α-Fe2O3) are particularly important in terms of technology [5][6][7]. Owing to their distinctive magnetic properties and favorable biocompatibility for potential applications in magnetic resonance imaging, drug delivery, and bioseparation, magnetite (Fe3O4) nanocrystals have received considerable attention [8][9][10].…”

In the present study, we investigated the crystallinity, surface morphology, and optical properties of iron oxide (Fe3O4) nanoparticles (NPs) formed by solvothermal synthesis. From powder XRD analysis, the Fe3O4 NPs were found to be an inverse spinel structure and highly crystalline nature. The surface morphology and particle size distribution were analyzed using a scanning electron microscope (SEM). The elemental compositions were confirmed using energy-dispersive X-ray spectroscopy (EDX). The optical characteristics of the Fe3O4 NPs were analyzed by UV-Vis spectroscopy. Overall, from the analysis, Fe3O4 NPs with tailored optical and structural properties can be easily formed by the solvothermal route to find potential applications in industries and the medical field.
