“…Further etching for 30 s and 60 s results in elongation of the etch pits, however, their shape remains the same. Similar phenomenon of etch pits elongation has been observed in NLO crystals reported in the literature [50][51][52][53]. It is noticeable that etch pits become more visible with an increase in etching duration which might have been facilitated due to segregation of impurities and dislocations.…”

Present investigation has been started to perform the comparative study of pure and glycine doped KH 2 PO 4 (KDP) single crystals grown by most commercial slow solvent evaporation technique. The grown crystals were subjected to single crystal X-ray diffraction analysis to determine their structural parameters. The linear optical studies of pure and glycine doped KDP crystal have been undertaken within 200 nm to 1100 nm wavelength range by means of UV-Vis studies. The enhancement in second harmonic generation (SHG) efficiency of glycine doped KDP crystal has been determined using a standard Kurtz-Perry powder test. The dielectric measurements have been carried out to explore the impact of glycine dopant on dielectric constant and dielectric loss of KDP crystal. The surface growth habitat and etch pit density of glycine doped KDP crystal have been evaluated using the results of microscopic etching studies. In light of obtained results the suitability of glycine doped KDP crystal for device applications has been discussed.

“…The etching analysis is therefore the most vital technique which helps to uncover the growth mechanism, surface habitat and micro‐structural defects associated with the crystal . Interestingly the revelation of typical etch patterns (spiral, rectangular, square, triangular, pyramidal, oval), growth hillocks and etch pits arising on crystal surface depends on selected crystal plane, etchant opted and the etching time which facilitates necessary information about the quality/purity of crystal . The pattern visualized under eyepiece of microscope (OLYMPUS U‐TV0.5XC‐3) before and after etching of pure and TA‐KDOP crystal surface has been captured in reflection mode with magnification of 10X.…”

High-end nonlinear optical devices demand superior quality KH 2 PO 4 crystal and to meet this necessity slow solvent evaporation technique is employed to grow optical quality potassium dihydrogen orthophosphate (KH 2 PO 4 , KDOP) crystal by doping tartaric acid (TA) and special attention is devoted to optimize the defect influenced properties of KDOP crystal. The incorporation of TA in KDOP crystal matrix is evaluated by employing energy dispersive spectroscopic technique. The crystalline phase and structural dimensions of pure and TA doped KDOP crystal is evaluated by means of powder X-ray diffraction analysis. The luminescence behavior of TA doped KDOP crystal is examined in visible region and violet colored emission is evidenced at 408 nm. The Vickers microhardness studies are carried out to uncover the constructive influence of TA on hardness and elastic stiffness coefficient of KDOP crystal. Impressive role of TA in minimizing defect density and improving the surface growth mechanism of KDOP crystal is explored by chemical etching analysis. The thermogravimetric analysis curve is traced within 30-650°C and TA doped KDOP crystal is found thermally stale up to 233°C. The results are appraised to propose the suitability of TA doped KDOP crystal for distinct applications.

“…A valley in the OA curve, as seen in Figure confirms the occurrence of strong RSA with positive nonlinear absorption coefficient (β) in the DEBM crystal. As can be seen, in the DEBM crystal, the absorption of the molecule in excited state is relatively higher than its ground state, which ensure the strong RSA effect. − With this respect, its exhibit exquisitely behavior in optical limiting, photonic and medical applications. , …”

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.
