摘要：
A new semi-organic nonlinear optical crystal of cobalt thiourea sulfate (CTS) has been grown by solvent evaporation solution growth method at room temperature. The unit cell parameters were evaluated by single crystal X-ray diffraction technique. The vibrational frequencies of various functional groups in the crystals have been derived from FT-IR analysis. The range and percentage of optical transmission are ascertained by recording the UV-VIS-NIR spectrum. The thermal behavior of the crystals has been investigated by DTA and TGA analyses. The mechanical property of the grown crystals has been analyzed by Vicker's microhardness method. The NLO property of the grown crystal has been confirmed by the Kurtz powder second harmonic generation (SHG) test. (c) 2007 Elsevier B.V. All rights reserved.
