title: Growth and characterization of novel organic optical crystal: Anilinium D-tartrate (ADT).
abstract: A novel organic nonlinear optical (NLO) crystal of anilinium d-tartrate (abbreviated as ADT) has been grown by the solution growth (slow evaporation) method at room temperature. Transparent crystals of dimensions 4mm×2mm×1mm were obtained. The grown single crystal was subjected to different characterization analyses in order to find out its suitability for device fabrication. Single crystal X-ray diffraction analysis reveals that ADT crystallizes in triclinic system with non-centrosymmetric space group P1. FTIR spectrum was recorded to explore information of the functional groups. The placement of protons and carbon was determined using (1)H NMR and (13)C NMR spectral analyses. The SHG output of ADT was recorded by Kurtz-Perry powder technique. The range of optical absorption was ascertained by recording UV-vis spectrum. The PL spectrum of ADT shows green emission. The dielectric behavior of ADT was investigated at 30°C, 70°C and 105°C are reported. Thermal properties were investigated by thermo gravimetric, differential thermal and differential scanning calorimetric analyses.
