Optical and Photoconductivity Studies on L-Arginine Benzohydrazide Non-Linear Optical Single Crystal

An organic nonlinear optical single crystal of L-Arginine Benzohydrazide (abbreviated as LABH) grown by the slow solvent evaporation method is reported. The properties of the grown crystal are determined by single crystal XRD, Fourier transform infrared spectroscopy (FTIR), UV-VIS spectroscopy, Kurtz and Perry technique, and photoconductivity studies. LABH belongs to the orthorhombic system with a P_(21) space group with lattice parameters a = 8.7740 A, b = 10.4434 A, c = 13.0843 A, α = β = γ = 90˚, V = 1198.92 A^3. The FTIR spectrum is taken to confirm the functional group present in the grown crystal. A UV-VIS spectrum is also taken for the sample, and it is found that it has very low absorption in the UV and visible region. It also has a wide transparency range. The powder technique is used to confirm the non-linear optical (NLO) property of the grown crystal and it is found that the NLO efficiency of LABH is 1.9 times that of potassium dihydrogen phosphate (KDP). Photo conductivity measurements are carried out in order to reveal the positive photoconductivity of the grown crystal.
