Linear and Nonlinear Optical Studies on Novel NLO BaTr Single Crystal

Transparent single crystal of Barium L-Tartarate (BaTr) was grown by slow evaporation Technique. Single X-ray diffraction study was carried out for the grown crystal. The FT-IR studies confirm the presence of barium and tartaric acid in the grown crystal. The band gap energy of the BaTr crystal was calculated from the optical absorption spectrum. Theoretical calculations were made to determine the optical constants like absorption coefficient (), extinction coefficient (K), Reflectance (R), refractive index (n), optical and electrical conductivity. Kurtz-Perry powder technique was carried out and the material is found to be exhibit nonlinear optical (NLO) property.
