“…In addition, CuS have been known to exhibit different absorbance edges in the electromagnetic spectrum (UV and VIS regions), [16]. This result is similar to the results of CuMnS thin deposited by the chemical bath method as reported by Salem et al [17]. The transmittance of the films was calculated using the relation given by [18].…”

Semiconductor thin films of CuMnS have been deposited onto conductive fluorine-doped tin oxide (FTO) glass substrate using an electrodeposition method to investigate their properties for possible applications. Copper sulfate, manganese sulfate and Thiourea were precursors used for sources of copper, manganese and sulphur ions respectively. The concentration of manganese ions was varied while keeping deposition voltage and time constant at 0.6 and 100 s, respectively. The films were characterized for optical, structural and morphological properties. The results obtained showed that the absorbance of the films is high in the visible (VIS) and near-infrared (NIR) regions but decreases towards NIR. The films transmittance is low in the VIS but increased in the NIR regions. The extinction coefficient is low in the VIS and NIR regions and decreases as concentration of manganese ion increased. The refractive index is high and initially increased slightly from 4.49 to 4.68 in the mid-VIS region while manganese concentration increased from 0.05 to 0.15 M and then decreased to the value of 2.73 as concentration of manganese ion increased further. The optical conductivity is high throughout the VIS and NIR regions while the optical bandgap energy is in the range of 1.5 to 2.05 eV and increases as manganese ion concentration increased. The XRD analysis showed that the deposited thin films of CuMnS are crystalline with average crystallite size and micro-strain in the range of 15.86 - 24. 45 nm and 3.97×10–3 - 6.13×10–3, respectively. The SEM results showed that the films are composed of particle sizes that are spherical in shape, uniform in sizes and densely packed together and consequently make the film surface rough. These properties exhibited by the films make them good materials for applications in photovoltaic calls, solar control coatings, photothermal applications and many other electronic devices that require high temperatures. HIGHLIGHTS This paper focused on the study of the effect of manganese ion concentration on the chalcogenide semiconductor thin films of CuMnS for possible device applications Electrodeposition method was used to fabricate the semiconductor thin films of CuMnS Optical, Structural and morphological properties of the thin films were characterized The deposited thin films of CuMnS were found to have good applications for photovoltaic cells and other optoelectronic device fabrications GRAPHICAL ABSTRACT

“…The XRD pattern of MnNbS showed peaks at 15.2, 29.2, 34.6, 50.0, 56.3, 60.1, and 64.9, corresponding to the crystal planes (002), (110), (200), (103), (110), (311), and (200). [ 33–35 ] The XRD spectrum of MnNbS/PANI displayed an additional peak at 25.1, which corresponds to PANI, [ 36 ] thereby confirming the successful synthesis of MnNbS/PANI . The synthesized materials’ resulting diffraction pattern agrees with previously published literature.…”

Supercapacitors (SCs), the most modern energy storage technology, have proven to be a viable solution for high-power applications. [1,2] High-performance SCs might have high specific capacitances, large power capability, and good cycling stability. [3,4] SCs are categorized into different types on the bases of energy storage mechanisms. In the electric double-layer (EDL) SCs, the charges are stored through the electrostatically or non-Faradic mechanism. In pseudocapacitors, the charges are stored chemically. In hybrid (symmetric or asymmetric) SCs, the charges are stored through electrostatically and chemically. [5,6] EDLCs preserve energy via electrostatic charge deposition at electrolyte/electrode interfaces, [7] while the pseudocapacitor is primarily due to the Faradic reactions at electrode surfaces. [8,9] A hybrid SC is an innovative and efficient energy storage device that integrates battery and supercapattery into a single device. [10] Because of

“…This shift towards the higher-energy wavelength of light implies band gap narrowing in the S2 sample, as confirmed in the analysis of the spectroscopic data using Tauc plots, shown in Figure 6c. The optical band gap energy E g of the prepared materials was estimated using the Tauc equation [51].…”

Rapid Bio-Assisted Synthesis and Magnetic Behavior of Zinc Oxide/Carbon Nanoparticles

The biomimetic synthesis of a ZnO/C nanocomposite has been achieved using the egg white-assisted self-combustion method. The characterization of this composite has been carried out using different techniques, such as XRD, FTIR, Raman, SEM/EDS and TEM. A comparative study was conducted between ZnO in the form of this composite and pristine ZnO, which was prepared via the same procedures but without the egg white. The resulting ZnO had a hexagonal structure, similar to wurtzite, with a P63mc space group. When this egg white method was used to produce a ZnO-based material, a ZnO/C nanocomposite was developed, and the ZnO’s crystallite size was significantly decreased. The structural properties—including the unit cell volume, strain, atom displacement and dislocation density—of this ZnO crystal are increased as a result of the presence of a C atom. On the other hand, the length of the Zn–O bond is reduced by the presence of the C atom. Results derived from a combination of Raman, FTIR, and EDS demonstrate that the carbonaceous layers and ZnO nanoparticles were integrated with a close interfacial contact. The preparation method used here brought about obvious changes in the morphological and magnetic behaviors of the as-prepared materials. Using a small amount of egg white resulted in the transformation of the particle’s shape from a hexagonal cone-type structure to an ellipsoidal structure. Based on an analysis of diffuse reflectance, the ZnO and ZnO/C band gap values were revealed using UV–VIS spectra. ZnO and ZnO/C exhibit band gap energies of 3.09 and 2.60 eV, respectively. A phase transition from weakly ferromagnetic to completely diamagnetic magnetic was discovered.
