“…The βc grows as hv increases until it hits a maximum (β cmax 4.6 cm/GW at 2.47 eV) at which point it decreases again. A similar response of βc with hv was discovered in several metal oxides, including PbO 2 /glass [46], MnO 2 /glass [47], and BiOI/FTO [48]. According to our previous work [17], the β cmax 4.36 cm/GW, β cmax 8.67 cm/GW and β cmax 13.85 cm/GW for SnO/glass, SnO/FTO, and SnO/ITO, respectively.…”

Tin oxide compounds have been highly studied due to their important properties. Tin Oxide (II) SnO compound is considered an ideal p-type conductive material, with large p-type carrier mobility. It is getting a lot of attention in next-generation electronic applications. In this work, the SnO thin film was deposited on the polyethylene terephthalate (PET) substrate by the thermal evaporation method. The X-ray diffraction pattern revealed the amorphous structure of the SnO/PET thin film. The purity of the SnO/PET film was confirmed using the Raman spectrum. An atomic force microscope was carried out to investigate the topography (roughness and particle size) of the obtained SnO thin film. The optical band gap $$E_{{\text{g}}}^{{{\text{Opt}}}}$$ E g Opt for SnO/PET thin film in the absorption region was estimated using Tauc’s equation. The refractive index for the SnO/PET thin film was estimated at the normal dispersion range by a single oscillator model. The dielectric optical properties of the SnO/PET thin film were estimated. The calculated third-order nonlinear susceptibility χ(3) and nonlinear refractive index n(2) were in the order of ~ 10−10 and ~ 10−9esu, respectively, within the photon energy range (0.5 to 4 eV). The Sheik–Bahae model was used to determine the nonlinear absorption coefficient βc for SnO/PET thin film. Based on these detailed results, the high nonlinear optical parameters pave the way for the probability of using the SnO/PET in flexible optoelectronics devices. Graphical abstract

“…BiOI, as a representative, has good optical, electrical, and magnetic properties and is mainly used as an ionic conductor and ferroelectric material and has applications in photocatalysis and other fields. [4][5][6][7][8] The pressure effects on BiOX materials have attracted much interest due to their robust layered structure at lower pressures. In the typical layered crystal structure of BiOX, [Bi 2 O 2 ] 2+ and X nÀ along the [001] direction, weak van der Waals forces connect two adjacent X nÀ layers indicating that the ionic radius and electronegativity of X nÀ significantly affect the phase transition behavior of BiOX materials under higher pressures.…”

“…The number of crystallites per unit surface area, N c , can be calculated using the following formula 27,28,30 : The values of δ, ε s , and Nc at different annealing temperatures are given in Table I. As seen in the table, the microstrain, dislocation density, and a number of crystallites all decrease with increasing annealing temperature, while the crystallite size increases.…”

In the current work, the structural and optical properties of thermally evaporated 3-(2-Benzothiazolyl)-7-(diethylamino) coumarin [Coumarin 6 (C6)] thin films on a pre-cleaned quartz substrate were studied as a function of the annealing temperature. The influence of annealing on the structural, morphological, and molecular structures was investigated by x-ray diffraction (XRD), atomic force microscopy (AFM), and Fourier transform infrared (FTIR) spectroscopy, respectively. The XRD and AFM results confirmed that the as-deposited and annealed films have nanostructural features (30.96–45.34 nm). Also, the increase in roughness of the C6 thin film surface resulted from particle agglomeration and coalescence. Optical constants of C6 thin films were derived from the transmittance T(λ) and reflectance, R(λ) measurements in the spectral range of 200–2500 nm. Analysis of the optical absorption coefficient data indicates that the type of electronic transition in these films is an indirect allowed transition. The estimated optical band gap was decreased from 2.12 eV to 2.01 eV as the annealing temperature was increased. Dispersion and dielectric parameters were determined as functions of the annealing temperature. Lastly, nonlinear optical parameters such as the third-order nonlinear susceptibility, χ(3) and nonlinear refractive index, n(2) were estimated and influenced by annealing temperature. The optical properties of C6 thin films were showed that C6 thin films would be used in a wide range of photonic applications Graphical Abstract
