Growth and characterization of novel organic optical crystal: Anilinium D-tartrate (ADT)

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 4 mm x 2 mm x 1 mm 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 H-1 NMR and C-13 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 degrees C, 70 degrees C and 105 degrees C are reported. Thermal properties were investigated by therm gravimetric, differential thermal and differential scanning calorimetric analyses. (C) 2011 Elsevier B.V. All rights reserved.
