Single crystals of pure and Neodymium (Nd3+) doped L-Arginine Acetate (LAA) were grown successfully by slow evaporation technique. In the present study, to improve the device characteristics of LAA crystals, metal dopant was incorporated into the pure crystals. The grown pure and doped LAA crystals were confirmed by X-ray powder diffraction studies. The pure and doped crystals were characterized by Fourier Transform Infrared (FT-IR), Fourier Transform Raman (FT-Raman) and Thermal studies. Absorptions of the grown crystals were analyzed using UV-Vis-NIR studies which revealed that these crystals possess minimum absorption from 250 nm to 1650 nm. Further, it was found that the optical properties were enhanced by the incorporation of the dopant. Hardness, dielectric and photoconductivity studies were also carried out for the pure and doped LAA crystals. Nonlinear optical studies of pure and doped crystals were carried out and it revealed that the dopant has increased the efficiency of the pure LAA crystal. ______________________________________________________________________________
