“…One of the finest ways to create high-quality, homogenous distributed Mn 3 O 4 thin layers is the spray pyrolysis technique. [19] In this current work, an in-depth study of the cobalt effect on the linear and nonlinear optical parameters of manganese oxide (0, 2, and 4 at%) thin layers is elaborated by the spray pyrolysis technique. Also, the physicochemical characteristics of the undoped and cobalt doped Mn 3 O 4 (0, 2, and 4 at%) thin layers were examined, as in their structural and morphological properties in order to correlate the crystallinity, the roughness, and the linear optical parameters with the nonlinear optical parameters of the Co:Mn 3 O 4 (0, 2, and 4 at%) thin layers.…”

In this study, undoped and cobalt‐doped manganese oxide Co:Mn3O4 (0, 2, and 4 at%) are elaborated by the spray pyrolysis procedure on glass substrates. The effect of cobalt doping concentrations on the structural, morphological, and optical features (linear and nonlinear) are investigated through the X‐ray diffractometer, Raman spectroscopy, Scanning Electron Microscopy with an attached energy dispersive X‐ray and UV–Vis‐NIR spectrophotometer. The XRD investigations exhibit a polycrystalline tetragonal structure for all Co:Mn3O4 and confirm by Raman results with the distinctive tetragonal mode A1g at 657 cm−1. The SEM images show an increase in roughness as cobalt doping concentration increases. The EDS quantitative analysis revealed the presence of manganese, oxygen, and cobalt. Furthermore, the optical investigation is pursued firstly through the linear optical that showed a decrease in the transmittance, and optical band gap energy as the cobalt concentration increased due to oxygen vacancies and defects and the increase of refractive index from 2.05 to 2.21. Second, the nonlinear optical parameters show a high value of the nonlinear refractive index 3.75 × 10−7 (esu) and the third‐order susceptibility χ3 = 2.2 × 10−8(esu) of Co:Mn3O4(2at%). These values put the Co:Mn3O4(2at%) thin layer as a candidate in the optoelectronic applications as a third‐order nonlinear medium.

“…Starting with the average crystallite size, its value decreases as the doping concentration increases, and it is validated by both methods. The crystallite size reduction from 22.42 nm (0 at%) to 19.958 nm (4 at%) can be assigned to the increase of tin ions in the Mn3O4 matrix, pushing the nucleation and growth of the nanocrystals to be prevented [12]. Further, the strain parameter exhibits a positive increase as a function of the doping rate of tin in the Mn3O4 lattice.…”

“…Undoped and tin-doped manganese oxide, Mn3O4: Sn, thin films (0, 2, and 4 at %) were elaborated by a chemical route presented in the spray pyrolysis technique that has been described in [12]. The sample preparation began with dissolving a calculated mass of Manganese (II) Chloride Tetrahydrate MnCl2 in 4H2O for a concentration of 0.1 M and a different ratio of Tin dichloride SnCl2 as a dopant element (0, 2, and 4 at %) After obtaining a homogeneous solution by stirring, the solution volume of 30 ml was carried out by a flow meter to a nozzle to be pulverized for 8 minutes on a 350 °C preheated clean glass substrate.…”

Undoped and tin doped manganese oxide, Mn3-xSnxO4, (x=0, 2, and 4 at %) thin films were successfully elaborated by the chemical route defined in the spray pyrolysis technique and deposited on glass substrates at a temperature of 350 °C. The physicochemical characterization of the thin films was performed using an X-ray diffractometer (XRD) that showed a polycrystalline tetragonal structure for all thin films. Raman measurement confirmed the vibrational mode, A1g, and the XRD results with the presence of no secondary phases. Scanning electron microscopy coupled with energy dispersive X-ray spectroscopy depicted the surface morphology and the elemental composition (Mn, O, and Sn) of the elaborated thin films. Finally, the optical analysis was carried out, and it showed an increase in the average transmittance of the Mn3O4: Sn (0, 2, and 4 at %) from 57.6 % to 62.2 % for 700 nm and an increase of their optical band gap from 3.27 eV to 3.61 eV. We note also a decrease of their dispersive energy parameter Ed from 5.44 eV to 4.86 eV, of their static refractive index n0 from 2.02 to 1.86, as well as for their nonlinear optical parameters presented by the nonlinear refractive index n2 from 1.14 10-11 to 0.51 10-11 and the third order susceptibility χ3 from 6.14 10-13 esu to 2.49 10-13 esu. These values can be correlated to the poor crystallinity and the tensile strain of the Mn3O4: Sn (0, 2, and 4 at %) thin films, as well as to the high order of the optical bandgap energy and the decrease of the linear refractive index of these films. Hence, these thin films can be used as material for nonlinear optical applications.
