Studies on the growth, structural, spectral and third-order nonlinear optical properties of Ammonium 3-carboxy-4-hydroxy benzenesulfonate monohydrate single crystal

•Single crystal of ACHBS size up to 20 × 14 × 5 mm3 was grown by solution growth method.•FWHM of ACHBS crystal was found to be 110 arc sec on (1 0 0) plane.•Cut-off wavelength of ACHBS was found to be 342 nm.•NLO parameters n2 = 1.204 × 10−11 m2/W, and β = 0.528 × 10−3 cm/W were measured.•ACHBS Vicker’s hardness test showed the mechanical tolerance load up to 125 g.

An organic nonlinear optical bulk single crystal, Ammonium 3-carboxy-4-hydroxy benzenesulfonate monohydrate (ACHBS) was successfully grown by solution growth technique. Single crystal X-ray diffraction study confirms that, the grown crystal belongs to P21/c space group. Powder X-ray diffraction and high resolution X-ray diffraction analyses revealed the crystallinity of the grown crystal. Infrared spectral analysis showed the vibrational behavior of chemical bonds and its functional groups. The thermal stability and decomposition stages of the grown crystal were studied by TG-DTA analysis. UV–Visible transmittance studies showed the transparency region and cut-off wavelength of the grown crystal. The third-order nonlinear optical susceptibility of the grown crystal was estimated by Z-scan technique using HeNe laser source. The mechanical property of the grown crystal was studied by using Vicker’s microhardness test.
