  • Nonlinear optical (NLO) crystals are classified into organic, inorganic and semiorganic crystals and these crystals are used in the fields of optical communication, optical computing, frequency doubling, optical data processing and opto electronics. In this work a semi-organic crystal namely tetrakis-thiourea nickel sulphate (TTNS) crystal was prepared. Slow evaporation technique was adopted to grow the single crystals of tetrakis-thiourea nickel sulphate after the growth period of 25 days. Bulk crystals were harvested from the supersaturated solution at room temperature. The harvested crystals have been subjected to various characterization techniques like XRD, FTIR, FT-Raman, and TG/DTA, Microhardness test, spectral, SHG, Z-scan and dielectric studies. The obtained results are presented and discussed.
