Physico-chemical, structural, optical and NLO studies on pure and La3+ doped l-arginine acetate crystals

Abstract Pure and La3+ doped single crystals of L-arginine acetate (LAA) have been grown well from through slow evaporation method in aqueous environment. The Crystalline nature can be confirmed by powder X-Ray Diffraction (XRD) Analysis. The function groups with possible stretching/bonding were identified through FTIR (Fourier Transform Infrared Spectroscopy) and Fourier Transform Raman Spectroscopy (FT-Raman) analysis. The good optical properties of La3+ doped LAA crystals were found through UV- Visible spectral analysis. Nonlinear optical (NLO) behavior through Kurtz’s method reveals that the dopant has increased the efficiency. Further, grown crystals has examined for thermal (TGA, DTA), mechanical (Vicker’s), dielectric (LCR) and photo conductive (picoammeter) properties enhanced with La3+ dopant and the results are interpreted and discussed.
