Abstract

The growth of 2-aminopyridine barium chloride (2APBC) crystal and its optical properties are discussed. 2APBC crystal was grown by slow evaporation solution growth technique at room temperature. FTIR analysis is effectively used for identifying the different molecular bonding and information about functional groups present in the synthesized compound. The powder sample of 2APBC crystal was used in Powder X-Ray Diffraction (PXRD) analysis to confirm the good crystalline nature of the sample. Single crystal X-ray diffraction analyses of grown crystal shows the unit cell lattice parameters value α = 5.281 , β = 5.410 , γ = 14.898 Å, α =β = γ=90º and volume V= 425.638 Å3, and confirms that 2-aminopyridine barium chloride (2APBC) crystal belongs to the orthorhombic crystal system with noncentrosymmetric space group P212121. Defect less; good quality 2APBC crystal was subjected to linear optical study. UV-vis-NIR spectroscopy study of the grown 2APBC crystal shows good transparency in the entire UV-vis-NIR region with lower cutoff wavelength 383 nm. Optical energy band gap (Eg) was calculated using UV spectrum data. Thermal behaviour of 2APBC sample was carried out using TGA and DTA analysis. The non-linear optical efficiency such as second harmonic generation was measured for 2APBC crystal and the result is compared with known inorganic reference material KDP. The dielectric constant is high at lower frequencies and decreases with increase in frequency trend were observed in dielectric polarization study. Hardness values of the grown crystal were estimated by Vickers's microhardness test.
