Linear Optical Studies of Nonlinear Optical Glycine - Phthalic Acid Single Crystal

Abstract

Good quality Glycine-Phthalic acid single crystals were grown by slow evaporation solution growth technique. Glycine and Phthalic acid materials were taken in the ratio of 1:1 for solution preparation with water as a solvent. Single crystal X-Ray diffraction of Glycine-Phthalic acid crystal was analysed to find lattice parameters, space group and crystal system. The study proves Glycine-Phthalic acid is orthorhombic crystal system and space group is Pbca. UV-Vis Transmission study was carried out on Glycine-Phthalic acid sample crystal. The lower cutoff wave length of the material is 234 nm. The optical band gap was determined as 4.979 eV. Extinction coefficient, Reflectance and refractive index of Glycine-Phthalic acid single Crystal were calculated and their variation with photon energy were analysed.
