“…The broad emission peak at 524 nm is related to the presence of defects (F − centers) associated with oxygen ion vacancies. These results are in good correlation with previous work [39][40][41]. In order to exclude the influence of the substrate, we also measured the PL spectrum of the glass substrate.…”

X-ray diffraction, atomic force microscopy, field emission scanning electron microscopy, UV-visible photometry, and photoluminescence measurements were used to investigate the surface morphology and structural and optical properties of MgO films. Magnesium oxide films deposited by the spray pyrolysis technique were studied. The substrate temperature was varied from Ts = 643 K to 693 K. Magnesium chloride hexahydrate (MgCl2 ·6H2O), dissolved in deionized water, was used as the precursor solution. It was established that the single phase films crystallize into a cubic structure with very fine crystallite size (about 2 nm). The optical band gaps of the samples were varied from 3.64 eV to 3.70 eV. Also, the films have a high level of transmittance of 90%. Photoluminescence spectra show the emission peaks at approximately 412 nm (3.00 eV) and 524 nm (2.38 eV). The peak with the energy of 3.00 eV is ascribed to holes trapped in magnesium ion vacancies acting as acceptors (F + center). The broad emission peak at 524 nm is related to the presence of defects (F − centers) associated with oxygen ion vacancies.

“…Although different kinds of MgO nanostructures have been fabricated by a variety of methods [10][11][12], reports on rapid synthesis of MgO nanostructures are sparse, and only our group have obtained them by direct current (DC) arc plasma jet chemical vapor deposition (CVD) [13]. The growth time does not exceed 10 min using this synthesis method; the growth rate of DC arc plasma jet CVD is much higher than that by other methods [14].…”

“…Today, pulsed laser and thermal evaporation, magnetron sputtering cathode and high frequency, chemical vapor deposition, spray pyrolysis, and others are used to obtain magnesium oxide films and nanostructures [1,[11][12][13][14][15]. Recently, much attention has been paid to non-vacuum methods to obtain films of metal oxides, one of which is a spray pyrolysis technique.…”

Abstract-In this paper we have conducted a comprehensive study of the structural and substructural characteristics of magnesium oxide films by X-ray diffraction analysis. Thin films MgO were prepared by spray pyrolysis technique from a magnesium chloride solution. Identified the phase composition, the lattice constant, crystallite size and coherent scattering domain size, microstrain level of the films. The optimal conditions for the application of homogeneous single-phase films of stoichiometric composition were identified.
