Publication date: Available online 11 April 2016 Source:Journal of Taibah University for Science Author(s): P. Baskaran, M. Vimalan, P. Anandan, G. Bakiyaraj, K. Kirubavathi, K. Selvaraju The amino acid based semiorganic nonlinear optical family single crystal of L- Leucinium perchlorate (LLPCl) belongs amino acid family was grown by solvent evaporation method at ambient temperature. Good optical quality single crystals up to a size of 6mm x 5mm x 3mm are obtained. The single crystal XRD analysis shows the grown crystals has monoclinic structure. Fourier transforms infrared (FTIR) spectral analysis and UV–visible spectral studies were also carried out. Microhardness mechanical studies show that hardness number (Hv) decreases with load for LLPCl single crystal by Vickers microhardness method. The dielectric properties of the grown crystal have been analyzed with the varying the frequency. The photoconductivity analysis gives the variation of the photocurrent and dark current. The nonlinear optical properties were studied using Kurtz and Perry powder method, the second harmonic generation efficiency was found to be 2.6 times higher efficiency compared to KDP crystals.
