title: Growth and characterization of nonlinear optical crystal Bis Thiourea Zinc Acetate (BTZA) in the presence of L-Proline.
abstract: Single crystal of 2 mol% L-Proline doped Bis Thiourea Zinc Acetate (BTZA), a semi organic nonlinear optical material has been grown using slow evaporation technique. Good quality single crystal with dimension 11×7×3 mm(3) was harvested after 30 days. The influence of amino acid L-Proline was studied for 1, 2 and 3 mol% L-Proline doped BTZA using Kurtz and Perry powder second harmonic generation test. This was compared with pure BTZA which confirms the enhancement of second harmonic generation property of L-Proline doped BTZA. Better enhancement was found in 2 mol% L-Proline doping. The grown crystal was characterized using single crystal X-ray diffraction, Fourier Transform Infra Red spectroscopy (FTIR) analysis, UV-Visible absorption and thermogravimetric analysis.
