This encouraging result of the Z-scan studies suggests that the VSNS crystal is a candidate material for photonics devices, optical switches, and optical power limiting applications. The second-order molecular hyperpolarizability γ of the crystal grown was 7.986 × 10 −34 esu. The third-order nonlinear optical property of VSNS was investigated in detail using a Z-scan technique with He–Ne laser at 632.8 nm. The grown crystals were identified by single crystal X-ray analysis. Variation of the dielectric response of the grown crystal was studied at room temperature. Investigations on Structural and optical properties of 4- chloro2-nitroaniline crystals for Nonlinear Optical. Laser damage threshold energy was measured using an Nd:YAG laser (1064 nm). NLO Properties of Coupled Oscillators and Crystals Garth J. Layer growth pattern was observed in chemical etching studies using a Carl Zeiss optical microscope at 50× magnification. The thermal stability of the crystal was analyzed by TG–DTA studies, and the hardness, Meyer index, yield strength, and elastic stiffness constant were estimated using a Vickers microhardness tester. The luminescence property of the crystal grown showed green emission radiation. Optical absorption was recorded using UV-Vis-NIR spectral analysis, and linear optical constants such as the absorption coefficient, band gap, extinction coefficient, refractive index and reflectance were calculated. The crystalline nature of the title material was analyzed by powder X-ray diffraction analysis, and the presence of expected functional groups and the molecular structure of VSNS was identified by FT-IR and 1H NMR spectroscopic studies. A single crystal X-ray diffraction study confirmed the crystal structure and morphology of VSNS. Solubility of the synthesized VSNS material was experimentally determined for various temperatures using a methanol–acetonitrile mixed solvent. Single crystals were grown in a mixed solvent of methanol–acetonitrile (1 : 1) using a slow evaporation method at room temperature.

A new organic stilbazolium derivative crystal 2-1-methyl-pyridinium naphthalene-2-sulfonate dehydrate (C 25H 23NO 5S♲H 2O) (VSNS) was synthesized successfully.
