“…From Table 5, the calculated values of the (NLO) parameters 𝜒 (3) and 𝑛 2 for 𝐵𝑖 2 𝑆 3 and 𝐵𝑖 2 𝑆 2.75 𝑆𝑒 0.25 are large and this can be related to the electronic and geometrical structure of these two materials.

This difference is due in particular to the quantum confinement effect in the nanocrystals.…”

Although the relevant properties of the bismuthinite 𝐵𝑖 2 𝑆 3 , it was recently approved that the substitution of Se atoms in the 𝐵𝑖 2 𝑆 3 lattice can significantly enhance its electro-optical properties.In the present work, a detailed study on the structural, electronic and optical properties of 𝐵𝑖 2 𝑆 2.75 𝑆𝑒 0.25 has been carried out based on first principle calculations. The simultaneous effect of Se-doping and spin-orbit coupling (SOC) on bismuth sulfide 𝐵𝑖 2 𝑆 3 was investigated. Our calculations show that 𝐵𝑖 2 𝑆 2.75 𝑆𝑒 0.25 exhibits a narrow direct band gap of 1.062 eV after inclusion of the (SOC). The calculation of the carrier effective masses indicates that 𝐵𝑖 2 𝑆 2.75 𝑆𝑒 0.25 may possess a high electron mobility material which is in accordance with experimental studies. The linear absorption optical spectra for both 𝐵𝑖 2 𝑆 3 and 𝐵𝑖 2 𝑆 2.75 𝑆𝑒 0.25 show that doping bismuthinite with (Se) increases the optical absorption coefficient in the visible range and takes a value up to 10 10 5 𝑐𝑚 −1 . In addition, the dielectric function, optical conductivity and the energy loss function of 𝐵𝑖 2 𝑆 3 and 𝐵𝑖 2 𝑆 2.75 𝑆𝑒 0.25 were also derived. The addition of the (Se) content induces a red shift in agreement with experimental studies. A noticeable effect of the (SOC) on the linear optical parameters was observed. The stability of the excitons was also studied by the estimation of the binding energy value. The dispersion energy parameters of 𝐵𝑖 2 𝑆 3 and 𝐵𝑖 2 𝑆 2.75 𝑆𝑒 0.25 were estimated using a single oscillator model. Some nonlinearities have been computed with and without inclusion of (SOC) showing that 𝐵𝑖 2 𝑆 2.75 𝑆𝑒 0.25 with large nonlinear optical parameters is promising candidate in photonic switching applications.

Although the relevant properties of the bismuthinite \({Bi}_{2}{S}_{3}\), it was recently approved that the substitution of Se atoms in the \({Bi}_{2}{S}_{3}\) lattice can significantly enhance its electro-optical properties. In the present work, a detailed study on the structural, electronic and optical properties of \({Bi}_{2}{S}_{2.75}{Se}_{0.25}\) has been carried out based on first principle calculations. The simultaneous effect of Se-doping and spin-orbit coupling (SOC) on bismuth sulfide \({Bi}_{2}{S}_{3}\) was investigated. Our calculations show that \({Bi}_{2}{S}_{2.75}{Se}_{0.25}\) exhibits a narrow direct band gap of 1.062 eV after inclusion of the (SOC). The calculation of the carrier effective masses indicates that \({Bi}_{2}{S}_{2.75}{Se}_{0.25}\) may possess a high electron mobility material which is in accordance with experimental studies. The linear absorption optical spectra for both \({Bi}_{2}{S}_{3}\) and \({Bi}_{2}{S}_{2.75}{Se}_{0.25}\)show that doping bismuthinite with (Se) increases the optical absorption coefficient in the visible range and takes a value up to \(10 {10}^{5}{cm}^{-1}\). In addition, the dielectric function, optical conductivity and the energy loss function of \({Bi}_{2}{S}_{3}\) and \({Bi}_{2}{S}_{2.75}{Se}_{0.25}\)were also derived. The addition of the (Se) content induces a red shift in agreement with experimental studies. A noticeable effect of the (SOC) on the linear optical parameters was observed.

“…The nonlinear refractive index coefficient γ we obtained is larger than those of Bi 3.25 La 0.75 Ti 3 O 12 ( γ = −1.915 × 10 −12 cm 2 /W) 25, Ba 0.6 Sr 0.4 TiO 3 ( γ = 6.1 × 10 −5 cm 2 /GW) 27 and Bi 2 O 3 ‐B 2 O 3 ‐TiO 2 ( γ = 8.85 × 10 −14 cm 2 /W) 28. The third‐order nonlinear susceptibility χ (3) of the BZN700 °C thin film is larger than that of Bi 2 S 3 ( χ (3) = 6.25 × 10 −11 esu) 29. As mentioned earlier, it is obvious that the real part of the third‐order nonlinear susceptibility χ (3) is larger than the imaginary part, which indicates that the nonlinearity is dominated by the nonlinear refractive behavior.…”

Bi 1.5 Zn 1.0 Nb 1.5 O 7 (BZN) thin films with good surface morphology were prepared on fused quartz substrates by pulsed laser deposition (PLD). The X-ray diffraction (XRD) analysis and atomic force microscope (AFM) surface morphology measurements were performed on the samples. The XRD pattern demonstrated that the films are cubic pyrochlore structure and well crystallized. The AFM analysis indicated that the films have less rough surface. The fundamental optical constants, such as band gap, the wavelength dependence of the transmittance, and the refractive index, were obtained. The sign and magnitude of both real and imaginary parts of third-order nonlinear susceptibility x (3) of the BZN thin films were determined by a single beam Z-scan technique performed at 1064 nm with a picoseconds laser. The third-order nonlinear refractive index coefficient g and the nonlinear absorption coefficient b of the BZN thin films are 4.06 Â 10 À15 m 2 /W and À1.45 Â 10 À9 m/W, respectively. The real part and the imaginary part of the third-order nonlinear susceptibility x (3) of the BZN thin films are 6.03 Â 10 À9 and 1.82 Â 10 À10 esu, respectively. The mechanisms of nonlinear refraction and nonlinear absorption were discussed. The results suggest that BZN thin film exhibit large third-order nonlinear optical properties and be a promising material for applications in nonlinear optical devices.
