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.
一种新型的有机非线性光学（NLO）晶体对氨基苯甲酸钠（简写为 ADT）已经通过室温下的溶液生长（缓慢蒸发）法生长出来。得到了尺寸为 4mm×2mm×1mm 的透明晶体。为了确定其是否适合器件制造，对生长的单晶进行了不同的特征分析。单晶 X 射线衍射分析表明，ADT 属于三斜晶系，非中心对称空间群为 P1。记录了傅里叶变换红外光谱以探索官能团的信息。通过（1）H NMR 和（13）C NMR 光谱分析确定了质子和碳的位置。通过 Kurtz-Perry 粉末技术记录了 ADT 的倍频输出。通过记录紫外-可见光谱确定了光学吸收范围。ADT 的光致发光光谱显示出绿色发射。报道了 ADT 在 30°C、70°C 和 105°C 时的介电性能。通过热重、差热和差示扫描量热分析研究了热性能。
