“…It may be noted that the efficiency of ESA, which is the primary cause for the RSA observed in our sample, is dependent on the input laser energy. The βeff values calculated from the Z-scan curves (Table 1) by numerically fitting the experimental data to Eqn.4 are either comparable to or better than those reported in literature for several novel materials, which include semiconductor core-shell nanostructures, atomic clusters of gold, noble metal nanosponges, doped carbon nanotubes, and graphene oxide [45,46,[54][55][56][57][58][59]. It is important to note that the linear transmission of our samples is perhaps the highest (87%) among the efficient optical limiters reported in literature.…”

Stable and efficient optical limiters for eye and sensor protection have been of great demand ever since the advent of high-power lasers. In this study, we report the preparation of highly stable hematene nanoflakes for optical limiting applications by a facile exfoliation method from a low-cost, non-van der Waals material. Optical and structural characterization have been carried out to confirm the structure, morphology and composition of the hematene nanoflakes. Open aperture Z-scan measurements have been carried out in near-transparent samples (87% linear transmission at the excitation wavelength of 532 nm), using 5 ns laser pulses. Despite the high transparency of the sample, a high nonlinear absorption coefficient of 12.5 cm/GW has been determined, signifying the potential of this material for fabricating highly efficient optical power limiting devices.

The excellent optical limiting behavior even at such very high LT values, ease of preparation, low cost, and most importantly the very high stability of the dispersion observed for more than one year (Figure S4) offers the possibility of fabricating efficient optical limiting devices using hematene nanoflakes for the protection of human eyes and sensitive photodetectors from hazardous laser radiation.…”

“…particularly, the localized states near the conduction or their valence band "tail states" could have a hard influence on the optical absorption which causes a decrease of the optical gap. However a resulting in small polarizability, it has a small effect on the refractive index; such tail states cause to increase the 'Urbach tail', but have a weak effect on the average gap E0 [28]. The static refractive index, n0, is determined from "Wemple -Di-Domenico" ( WDD) dispersion parameters, E0 and Ed by the following relation [28]:…”

The structural characterization of a new organic compound (3, 5-bis (4-chlorophenyl)-4,5-dihydro-1H-Pyrazole) was analyzed experimentally by 1HNMR and FT-IR spectroscopic technique. The analysis of HOMO-LUMO and natural bond orbital are investigated to study the charge transfer interactions which is leading to the properties of nonlinear behavior. linear optical properties of anew organic compound / Poly (O- Methoxyaniline) (POMA) film was studied using Wemble and Didomenico (WD) technique to estimate the refractive index n and other optical constant such as the oscillation energy E0, the dispersion energy Ed, and the lattice dielectric constant. Measurements of the thermally induced optical nonlinearity of novel organic compound (3, 5-bis (4-chlorophenyl)-4, 5-dihydro-1H- Pyrazole) in an organic solvent (N-methyl-2-pyrrolidone) NMP)) was studied through an excitation source (continuous wave diode laser at the wavelength of 473 nm) in the case of the solution and a conducting polymer film. The Z-scan technique was used to measure the nonlinear refractive index )) to obtain the optical response of prepared material. The prepared sample illustrated negative and large values in the order of 10− 7 cm2/W and reverse saturable absorption )RSA) with large values of the nonlinear absorption coefficient in the order of 10− 3 cm/W. The nonlinear refractive index was determined and varied as a response to different concentrations. The determination of the figure of merit (W) and nonlinear coefficients indicate that the compound is a promising candidate for applications in the nonlinear optics field.
