Influence of Cd-content on structural and optical dispersion characteristics of nanocrystalline Zn1−Cd S (0 ⩽x⩽ 0.9) films

Effect of copper concentration on the physical properties of ZnS:Cu alloys prepared by chemical bath deposition

“…It is found that M À1 and M À3 values are in the range (2.63-4.09) and (0.09-0.79), respectively, which are consistent with that obtained by Farag et al [36]. The effect of Cu concentration on the electric susceptibility v e ð Þ as well as the real dielectric constant e r ð Þ is discussed according to the Spitzer-Fan model [37]:…”

“…The dispersion parameters of ZnS:Cu thin films can be obtained by plotting n 2 À 1 ð Þ À1 versus hm ð Þ 2 and fitting the experimental data to straight line, as shown in Fig. 12 For further optical analysis, the moments of optical dispersion spectra M À1 and M À3 are related to E 0 and E d by the following relations [36]:…”

“…The single oscillator parameters E 0 and E d can be used for the determination of the third-order non-linear optical susceptibility v 3 ð Þ , which is a significant factor indicating whether the films are suitable for optical switching and photonic devices. It can be calculated by using the following relation [36,39]:…”

Study of optical properties of thermally evaporated ZnSe thin films annealed at different pulsed laser powers

“…where B = 1.7× 10 ିଵ [esu] and is independent on the frequency, while n(0) is the static refractive index of samples [52,53]. It is worthy to mention here that the third-order nonlinear susceptibility χ (3) can be generalized for both the crystalline and amorphous materials [50][51][52][53].…”

“…It is worthy to mention here that the third-order nonlinear susceptibility χ (3) can be generalized for both the crystalline and amorphous materials [50][51][52][53]. The values of χ (3) were calculated and listed in …”
