Abstract In this paper, undoped and doped (Fe, Co and Fe-Co) nickel oxide (NiO) nanostructures have been synthesized using co-precipitation method. Prepared samples were characterized for the structural, compositional, morphological and optical properties using x-ray diffraction, scanning electron microscopy (SEM), Energy dispersive spectrocopy (EDS), UV-visible spectroscopy and photoluminescence spectroscopy. Structural analysis confirmed the single cubic phase formation of undoped and doped samples. Defect chemistry showed that Fe-Co co-doped NiO possesses a lower density of defects than other samples. SEM results revealed the agglomeration of particles. EDS results confirmed the presence of Ni, O, Fe and Co in the respective undoped and doped samples. Optical analysis revealed the band edge shifts with the incorporation of dopants in the NiO crystal lattice confirmed the variation of band gap energy. Emission peaks were observed in the UV and visible regions. The Incorporation of dopants in the crystal lattice causes variation of emission centers. Surface oxygen vacancies and imperfections significantly impact the emission characteristics of NiO. Variable spectral response of NiO with dopant incorporation has potential for optoelectronic applications.

Biodegradable polymer nanocomposites have gained attention in recent years owing to their antimicrobial activity. The article summarizes recent developments in improving antimicrobial, mechanical and barrier properties of biodegradable polymers chitosan, cellulose, gelatin and starch. ZnO, TiO2, reduced graphene oxide and silver reinforced biodegradable polymer nanocomposites exhibit improved tensile strength due to intercalation of nanomaterials into the polymer matrices. Silver nanoparticle reinforced polymer nanocomposites have shown significant antimicrobial properties against various strains of bacteria and fungi. Although, development of antimicrobial nanomaterials embedded packaging films has helped to augment shelf-life of food, leakage of nanomaterials into the packaged food remains an area of concern.

In this work, photo- and temperature-dependent electrical properties of thermally deposited WTe2 thin film have been reported. The n-type behaviour of WTe2 film of thickness ~ 122 nm has been observed. The dark conductivity analysis revealed that thermally activated conduction mechanism is responsible for charge carrier transport. In the presence of light, WTe2 shows higher current than dark conditions response towards light with two activation energies of ~ 0.374 eV and 0.692 eV signifying the dominance of bimolecular recombination under light illumination. On–off cycle determined the respective current variation with different light intensities. The fabricated device possesses responsivity ~ 0.36 mA/W and detectivity of ~ 3.2 × 109 Jones.

Abstract Cerium oxide (CeO2), also known as, ceria, is a well-known n-type semiconductor material. It finds potential roles in various field applications such as catalysis, sensing and antibacterial. It is widely used as a photocatalyst for treatment of waste water pollutants, because of the variable oxidation state of cerium i.e. +3, and +4. Many reports are available in literature which deals with the synthesis and properties of CeO2. The properties of CeO2 are highly dependent on the synthesis conditions such as precursors, additives, calcination temperature and type of synthesis route. In this review article, synthesis of CeO2 by various chemical routes are discussed in detail.

Abstract The present research aims to study the structural, morphological and bandgap studies of 1mol% Ce doped Gd2O3 samples. Gd1.99Ce0.01O3 sample was synthesized via hydrothermal method. The crystallinity, phase and crystallite size are determined using X-ray diffraction (XRD) patterns. X-ray diffraction patterns revealed the development of pure crystalline phase Gd2O3 sample. The morphology of the synthesized sample is examined using Field emission scanning electron microscope (FESEM) micrographs and elemental composition by energy dispersive spectroscopy (EDS) spectra. FESEM results confirmed the formation of rod shape of the synthesized samples. The bandgap studies are done using UV-Visible spectroscopy. The synthesized samples are the potential candidates for various biomedical, and optoelectronic applications.

The electrical properties of boron carbon nitride (BCN) were studied using a thin-film device of the material. Fourier transform infrared spectroscopy spectrum demonstrates the atomic intermixing of boron, carbon, and nitrogen in BCN film. Also, bonding configuration and linkage of carbon with more electronegative nitrogen atoms were observed. X-ray photoelectron spectroscopy analysis shows the dominance of graphitic carbon and h-BN domains in the deposited film. The photoluminescence studies of the deposited film show a broad emission in the ultraviolet and visible region due to band-to-band transition of BCN and defect states-induced emission, respectively. The deposited film shows the low dielectric constant value of 2.97 with the variation of temperature and frequency. Low-temperature studies show an increase in conductivity (obtained σ = 2.98 × 10–4 S/cm) from 223 to 273 K due to the dominance of BCN superlattice. In contrast, a reduction in conductivity is observed from 273 to 300 K with the increase in inter-grain boundary area and the ascendency of the boron nitride domain.
