Abstract

TTCS single crystals have been grown successfully by slow evaporation technique from aqueous solution at room temperature. The functional groups present in the grown material have been confirmed by FTIR analysis. In order to find the lattice parameters the single crystal x-ray diffraction analysis has been taken. The crystalline nature of the material is determined with the help of powder x-ray diffraction patterns, whereas, the lattice parameters are found out by single x-ray diffraction analysis. The Second Harmonic Generation (SHG) test has been done to reveal the NLO property of the grown crystals. The mechanical properties of the grown TTCS crystal were studied by Vicker Hardness test. TGA/DTA curves establish the thermal properties of the grown crystal. UV-visible spectrum confirms that the crystal has lower cutoff in the uv region and higher cut-off frequency in the mid-IR region. TTCS is another new potential semi organic nonlinear optical material having better nonlinearity and a low UV cut-off.
