Abstract: L-valine barium chloride (LVBC), 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 LVBC was identified by FTIR studies. The UV-VIS-NIR studies reveal that the crystal has a low UV cut-off of 202.69 nm and has a good transmittance in the entire visible region. The photoluminescence spectra reveal violet emission at 395nm, 430nm, and 437 nm respectively. The second harmonic generation efficiency was determined and is about 0.693 times that of the KDP crystal.
