Noncentrosymmetric crystal of Nicotinium p-Toluenesulfonate (NPT) was grown by slow evaporation growth method. The crystal structure was determined by Single crystal X-ray diffraction and it confirms that the grown NPT crystal belong to orthorhombic crystal system with noncentrosymmetric space group Pmn21. The vibrations of the functional groups and chemical bonds were analyzed by FTIR spectrum. The grown NPT compound is thermally stable upto 60 °C and its decomposition was elucidated by Thermal analysis. The grown NPT crystal posses wide optical transmittance in the visible region and lower cut-off wavelength is found to be 335 nm. The emission region of grown NPT crystal was identified by photoluminescence emission spectrum. The surface with stand stability from damage induced by high power laser beam for grown NPT crystal was studied. The dielectric parameters of the grown NPT crystal are inversely proportional to the applied frequency. The grown NPT crystals belong to hard material category. The SHG efficiency of the grown NPT crystal is 0.75 times than that of KDP.
