Synthesis and Characterization Studies of L-Alanine Alaninium Nitrate NLO Crystal

Jayanthi Palaninathan, Aravind K

Abstract: L-alanine alaninium nitrate (LAAN), an organic nonlinear optical material was grown by slow evaporation technique at room temperature. The grown single crystal structural information was derived from X-ray Diffraction. The crystal represents the orthorhombic crystal structure. The mode of vibrations of different molecular groups present in LAAN was identified by FTIR studies. The UV-VIS-NIR spectrum reveals that the crystal has a low UV cut-off of 204.20 nm and has a good transmittance in the entire visible region. The photoluminescence spectra reveal green and blue emission at 439 nm and 468 nm respectively. The second harmonic generation efficiency was determined and is about 0.693 times that of the KDP crystal.
