| Abstract: | L-asparagine monohydrade thiocyanate (LATC), which is potentially a non-linear optical crystal, was grown by the conventional slow evaporation solution technique (SEST) using doubly de-ionized water at room temperature. The lattice parameters were found by using single crystal X-ray diffraction analysis. Perfection of the grown crystal was confirmed by powder X-ray diffraction. The various functional groups were identified from FT-IR analysis. The optical parameters, such as the optical absorption, the band gap, photoluminescence and second harmonic generation (SHG), were analyzed on the grown crystal. The induced surface laser damage threshold was measured using a Q-switched Nd:YAG laser. The thermal behavior and stability of the grown crystal was analyzed by TG/DTA analysis. The dielectric constant (εr) and dielectric loss (tanδ) as a function of frequency has been investigated at different temperatures. The mechanical property of the grown crystal was studied using the Vickers micro hardness method. |
