| Abstract: | The Triethanolamine picrate (TEAP) single crystal was grown by slow evaporation technique. The grown crystal crystallizes in monoclinic system and P21/C is the space group determined by Single crystal X-Ray diffraction method. The vibrational modes and functional groups were elucidated from Fourier Transform InfraRed (FTIR) spectra and Fourier Transform Raman (FT-Raman) spectra. The Ultraviolet - Visible (Uv-Vis) studies accomplished the excitation wavelength of the grown crystal is around 203 nm and 354 nm and it is suitable to exhibit second harmonic generation signal. From the absorption data, remarkable optical properties such as optical band gap energy, extinction coefficient were evaluated. The mechanical strength of the grown crystal was examined by Vickers micro hardness test. The temperature of decomposition was confirmed by Thermo Gravimetric / Differential Thermal Analysis (TG/DTA). Kurtz and Perry technique were confirmed the Non-Linear Optics (NLO) property of the crystal. The electrical properties were explained using Dielectric studies. |
