An investigation on photoacoustic spectroscopy and dielectric properties of sulfanilic acid nonlinear optical single crystal for different applications

Sulfanilic acid (SA) crystal has been very well established as an excellent material for the applications such as photonic, electro-optical and harmonic generation in non linear optics (NLO). This article is deliberated on good quality SA single crystal which has been grown by slow evaporation solution technique as it is a prominent NLO material. After the growth period of 95 days, a transparent SA single crystal has been collected with the dimension of 9 × 9 × 2  mm³. The grown crystal has been subjected to photoacoustic spectroscopy (PAS) and impedance analyses. The study of PAS has been utilized to find out thermal diffusivity and the observed result qualifies the crystal to be suitable for lasers and high temperature related applications. Impedance analysis has been implemented for the grown SA crystal for various values of temperature and it comes out with good results so that it could be a candidate for few applications in the field of microelectronic and electro-optical industries.
