“…(1), the value of n (2) 0 were found to be 1.96, 1.88, and 1.73 for S1, S2, and S3 films, respectively, which shows a regular decreasing trend with increasing Mg concentrations in the samples and reaffirms the well-known fact that the refractive indices decreases with increasing band gap. This observation agrees well with the experimental observations of Amirhaghia et al [11] and Yang et al [12] as well as the theoretical calculations of Murtaza et al [13].…”

We report the nonlinear optical properties in pulsed laser deposited pure and Mg‐doped ZnO films at an excitation energy (≈1.95 eV) much smaller than the band gap energies (≥3.24 eV) of the films. The nonlinear absorption is attributed to the presence of defect states whereas the nonlinear refraction arises due to thermal lensing effect. Larger contribution of nonlinear absorption compared to nonlinear refraction suggests the utility of Mg‐doped ZnO films in optical limiting device applications.

In the present article, we have revisited the electronic band gap nature of ZnO x S 1Àx (0 x 1) with the recently developed modified Becke and Johnson exchange potential and the calculated band gaps are found consistent with the experimental results. We expect that the band gap bowing parameter obtained in the present work will be close to the experimental one. As the optical properties of ZnO x S 1Àx (0 x 1) are very important, therefore different optical parameters like dielectric functions, refractive index and reflectivity are also calculated. The results are illustrated in terms of band structures, band gap energy as a function of oxygen composition, total and partial density of states.
