Studies on Growth, Spectral, Thermal, Mechanical and Optical Properties of 4-Bromoanilinium 4-Methylbenzenesulfonate Crystal: A Third Order Nonlinear Optical Material


Mat. Res.




Abstract 4-Bromoanilinium 4-methylbenzenesulfonate (4BPTS) single crystal was successfully grown from ethanol by slow evaporation method at room temperature. The structure of grown crystal was confirmed by single crystal X-ray diffraction studies. The presence of functional groups of grown crystal was confirmed by the Fourier transform infrared spectroscopy (FTIR) spectral analysis. UV-Visible absorption study was performed on the grown crystal to determine the cut-off wavelength. The thermal stability of the grown crystal was investigated from the Thermogravimetric analysis (TGA)/ Differential thermal analysis (DTA) analysis. The mechanical behaviour of grown crystal was studied by using Vicker's microhardness test. The third order non-linear optical properties of 4BPTS were investigated by Z-scan technique with He-Ne laser radiation and the corresponding non-linear refractive index and absorption coefficients were also calculated.
