Abstract

In this present work, we report the successful growth of zincchloride added thiosemicarbazide(TSCZC) crystals grown by slow solvent evaporation at room temperature. Good crystaline Pnma space group with orthorhombic structured non centrosymmetric crystal verified by powder-x ray diffraction was also characterised by Fourier Transformed Infrared, Differential Scanning Calorimetry and dielectric analysis to identify the presence of various functional groups with bonding types, thermal stability, and dielectric properties. Vast transparency in the whole visible region with 4.54 eV band gap for λmin = 273 nm suggests the utility of the crystal for non linear optical applications. Kurtz-Perry SHG test shows 0.317 times higher efficiency than reference KDP.Z scan analysis exhibits higher third order nonlinear optical susceptibility χ(3) = 3.266 ×10-6 esu with non linear refractive index(n2) = 3.33 ×10-9 cm2/W.Self defocusing nature and Reverse Saturation Absorption(RSA) styles are the added advantages of the grown TSCZC metal organic crystal for its utilisability in Non Linear Optical and photonic device applications.
