“…This can be attributed to the considerable influence of interface energy. Little voids due to lateral surface diffusion of the film particles and possible elimination of some trapped vacancies during annealing result in good adhesion to the substrate . However, excessive heating of nanostructured layered materials does not go without leaving behind some effects, Ho et al .…”

“…This might be enhanced by the post‐deposition heat treatment. High transmittance of MgO film due to increased oxidation temperature and reduced grain size has been reported . Absorption coefficient, α, was estimated from the UV–VIS data using the relation ∝ ≅ − ln T , where T is the film transmittance which is highly dependent on the morphology .…”

“…Emission of secondary electron from solids can also find application in devices such as electron microscopes and electron multipliers . Its high density, transparency, and relatively low refractive index (~1.7) near to that of glass also make it suitable for many other advanced optoelectronic applications . MgO also has a unique ability to pin the magnetic flux lines within a high‐temperature superconductor and improves its critical current densities …”

Growth conditions, structural, and optical properties of MgO nanostructure have been investigated. Surface composition and shift in binding energy of Mg at 50.8 eV due to oxidation were examined by core-level spectroscopy. The SEM showed that the film is dense, and grain growth and crystallinity are enhanced by post-deposition annealing. Grain distribution was appraised within the confinement of 24.51 μm 2 from the selected scan areas. X-ray diffraction studies indicated prominent peaks, which are attributed to (111), (200), and (220) reflections from fairly crystallized and randomly oriented MgO thin film. Plane (111) is found to be the preferred orientation of the film. The film transmitted well across the visible spectrum and the estimated energy band gap is 5.41 eV. Absence of catalyst in the electrolyte solution aided the purity of the sample.

“…(NaCl-type) crystal structure, high thermal stability, predominantly ionic nature, and insulating behaviour [1]. MgO has been extensively used in catalysis, toxic waste remediation, antibacterial materials, refractories, paints, and superconductors due to its unique optical, electronic, magnetic, thermal, mechanical, and chemical properties [2][3][4][5][6][7][8]. Recently, it has found promising application in plasma display panels [9].…”

An attempt has been made here to synthesize nano-powders via sol-gel process. These powders are shown to possess an f.c.c. (NaCl-type) structure with a typical lattice parameter of Å for when decomposition of dried oxalate gel product is carried out at 600°C for 2 h in air. Moreover, they exhibit (i) clusters/agglomerates of nanosize particles and (ii) high BET specific surface area (123.0–135.5 m2/g). Also, the infrared absorption spectra reveal their strong affinity to water. The UV-Vis absorption peaks appearing at ~202 nm, 296 nm, and 379 nm are associated with oxygen defect centres and correspond to the electronic transitions (i) (, , or ), (ii) (, or ) and (iii) (), respectively. The incorporation of Ni2+ ions causes some modifications in the energy levels and the optical absorbance characteristics. The suppression of a strong broad emission peak at 440 nm and improvement of a weak band at 400 nm in the photoluminescence (PL) spectrum arise due to decrease in population density of centres (or F+ dimmers) and emergence of additional F+ centres, respectively with increase in nickel content.
