Lanthanum doped L - alanine tartrate (LAT) was synthesized by solution method and solubility study was carried out. Single crystals of LAT were grown by slow evaporation method. The cell parameters were determined by single crystal X-ray diffraction study. Transparency range of the crystal was determined using UV-VIS-NIR spectrophotometer. The functional groups of LAT crystals were analyzed by FT-IR spectroscopy. The hardness of the material was measured by a Vickers micro hardness tester. The dielectric response of the crystal was investigated in the frequency region of 50 Hz – 500 KHz. The nonlinear optical property was tested by Kurtz-Perry powder technique for second harmonic generations.
