title: Synthesis, growth and characterisations of semi-organic nonlinear optical crystal glycine barium nitrate (GBN).
abstract: Transparent crystal of glycine barium nitrate (GBN) has been grown from aqueous solution by slow evaporation technique at room temperature. Powder XRD study reveals the crystalline nature of the grown sample. Single crystal XRD study shows that the GBN belongs to orthorhombic crystal system. FTIR spectral study confirms the presence of the functional groups in the grown crystal. The presence of wide transparency window in the UV-visible region makes GBN crystal suitable for opto-electronic device applications. The grown sample has SHG efficiency is 0.8 times that of standard KDP crystal. Dielectric studies reveal that both dielectric constant and dielectric loss decreases with increase in frequency. Photoconductivity study confirms the negative photoconducting nature of the crystal.
