Abstract
A new semiorganic nonlinear optical material anilinium perchlorate was grown by the slow evaporation technique using water as solvent. The solubility and meta stable zone width were determined. The anilinium perchlorate crystal belongs to orthorhombic system with noncentrosymmetric space group P212121. The presence of various functional groups was identified by FT-IR FT-Raman spectrum. The morphology of the anilinium perchlorate crystal was studied. From this morphology, anilinium perchlorate crystal plate was cut along three prominent planes, such as (001), (010) and (20−1). The thermal stability of the crystal was determined using TG–DTA studies. The hardness, laser damage threshold, transmittance, reflectance, experimental refractive index of the crystal was found. The particle size dependent second harmonic generation efficiency for anilinium perchlorate was evaluated by Kurtz–Perry powder method using Nd:YAG laser, which established the existence of phase matching. The third order nonlinear refractive index and nonlinear absorption coefficient of the grown crystal were measured by Z-scan studies.
