摘要

A novel semi-organic nonlinear optical crystal of Ni2+ doped Di Zinc Tetra Glycinate Dihydrate has been grown using the slow evaporation solution growth technique. The single-crystal X-ray diffraction analysis determined the crystal system and lattice parameters. EDAX analysis confirms the presence of dopant Ni2+ion in the host crystal DZTGD. Fourier transform infrared (FTIR) studies and Raman studies confirm the various functional groups present in the grown crystal. The transmittance and absorbance of electromagnetic radiation are studied through the UV-visible spectrum. The thermal stability of the grown crystal was determined through TG/DTA examination. The Z-scan experiment was conducted to analyze the crystal for third-order NLO behaviour and it was used to calculate the values of the nonlinear absorption coefficient, nonlinear refractive index, and third-order nonlinear susceptibility. Third-generation harmonic studies on the Kerr effect and two-photon absorption reveal that Ni2+doped DZTGD is an excellent material useful for the fabrication of NLO devices due to its nonlinear response characteristics.
