Paper Details

New nonlinear optical single crystal of 2-Amino-6-methylpyidinium 6-Aminocaproate (2A6M6A) wasgrown by slow evaporation method using water as a solvent. The grown 2A6M6A crystal was characterized andconfirmed by Single crystal X-ray diffraction. It is a monoclinic structure with noncentrosymmetric space group P. Thelattice parameters of the grown crystal is found to be a = 8.54 Å, b = 5.89 Å, c = 15.24Å, α = γ = 90,  = 102.86 andvolume V = 748 Å3. The crystalline perfection was confirmed by Powder X-Ray diffraction analysis. The grown 2A6M6Afunctional groups and chemical composition were confirmed by the FT-IR and Laser Raman spectroscopy analysis.Optical studies are important criteria for the optical applications. The grown crystal was subjected to the UV analysis,from the figure it is observed that the cut off wavelength at 295 nm and there is no absorption in the entire visible region.The band gap of the grown 2A6M6A crystal is found to be 4.13 eV. The photoluminescence spectra give the qualitativeand quantitative analyses of 2A6M6A grown crystal. The excitation wavelength at 386 nm and the high intensity peakwas observed at 460 nm. Thermal stability of the material is confirmed by the thermal analysis; it is stable upto 193C.Nonlinear optical studies confirmed by the Kurtz-Perry powder SHG test. The grown 2A6M6A crystal is 2.6 times higherthan that of KDP Crystal.
