“…From the following equation, it is possible to calculate the disorder in the system as a function of α , which corresponds to the transition between the localized states and the extended state of the conduction and valence bands, through a parameter known as the Urbach energy ( E u ). 41,44 where h , ν , α 0 , and E u represent Planck's constant, the incident frequency radiation, a constant and Urbach energy, respectively. The width of the elongated tail of the localized states in the forbidden electronic band gap (Urbach energy or band tail energy) was obtained by plotting a graph between the ln of the absorption coefficient α vs. hν .…”

“…The behavior of the crystal under strong electric field gives us a provision to evaluate the power dissipation factor which plays a significant role in Laser applications. [ 35,36 ] The dielectric studies of the grown ABAQ crystal was carried out at room temperature for varying temperatures of 33, 50, and 70 °C. For the measurement, an optically good quality crystal sample was coated with silver paste on either side to form electrodes of a parallel plate capacitor.…”

Good quality single crystals of a non‐linear optical (NLO) material, quinolinium 4‐aminobenzoate (ABAQ), are grown by employing solution growth technique. The crystal structure is confirmed via single crystal X‐ray diffraction studies. Grown crystals of the ABAQ compound are characterized by powder X‐ray diffraction, Fourier transform infrared, thermal analysis, and mechanical studies. Ultraviolet–vis–near infrared (UV–vis–NIR) and photoluminescence spectra reflect the optical transmission range of the obtained compound. Dielectric studies and laser damage threshold measurement are carried out to verify the non‐linear activity and surface resistance of the grown crystal. From the Kurtz Perry powder technique, the second harmonic generation efficiency of the ABAQ compound is estimated to be 90% that of the standard potassium dihydrogen phosphate. Z‐Scan technique is performed to investigate the non‐linear behavior of ABAQ crystal. The suitability of ABAQ material for optical limiting and switching applications is also verified. Computational analysis performed upon the stable geometry of ABAQ molecule using density functional theory strongly supports the experimental findings with a significant chemical background. The non‐linear behavior of the title compound is determined by investigating various non‐linear optical (NLO) parameters of electric dipole moment, polarizability, and hyperpolarizability. Based on these inferences, the ABAQ material can be declared as a promising material for optical limiting and switching applications in optoelectronics regime.

“…mainly depend on the quality and structural perfection of the materials. Moreover, chemical etching has an influence to develop the growth features on the crystal surface. , The patterns of etch pits was qualified with three factors: (1) type of solvent (etchant), (2) etching time, and (3) crystal faces. The chemical etching study of DEBM crystal was characterized by using ethyl acetate as an etchant for different intervals of 15 and 30 s. After that, the etched surface of the crystal was gently wiped with the help of tissue paper, which can contribute their microstructures via reflection mode of an optical microscope.…”

Bulk organic nonlinear optical (NLO) single crystals of DEBM (2-[4-(diethylamino)benzylidene]malononitrile), with sizes up to 22 × 5 × 12 mm 3 have been grown in ethyl acetate solution by the slow evaporation method. The lattice parameters and crystalline purity of the titled crystal were measured by single crystal X-ray diffraction and powder XRD, respectively. The morphology of the grown crystal was portrayed by WinXMorph program. Fourier transform infrared (FT-IR) spectral studies have been performed to identify the functional groups. The molecular structure was confirmed through 1 H NMR. UV−vis−NIR spectral analysis signifies that the DEBM crystal is transparent in entire visible and near-infrared region, which has a lower cutoff wavelength around 476.8 nm. The optical band gap (E g ) was estimated from the Tauc plot and was found to be about 2.68 eV. The low value of the dielectric constant (ε r ) of DEBM suggests that it has a possible strategy toward the microelectronics industry. Thermal stability and melting point (137.8 °C) were studied with TGA−DSC analysis. The laserinduced damage threshold (LDT) experiments showed that the grown DEBM bulk crystal possess an excellent resistance to laser radiation with a high threshold up to 1.95 GW cm −2 , it is still better compared to other organic and inorganic NLO materials. The third-order optical nonlinearities of the DEBM crystal was confirmed by the single beam Z-scan technique. All these results demonstrate that the organic crystal DEBM is promising for NLO applications.
