ABSTRACT New organic crystals of L-leucine thiourea were grown by slow evaporation method from the aqueous solution. Different characterization studies were carried out for the grown crystals, such as UV-Vis, FTIR, XRD, TG-DSC and SHG. Identification of materials can be done by the FTIR and X-ray diffraction analysis. The grown crystal belongs to monoclinic was determined using XRD. Using TG-DSC analysis the thermal stability can be determined and it was absorved that the crystal was stable upto 205̊ C. The SHG efficiency of the grown crystal was found to be noted that highly pronounced on compared with urea and KDP.
