Single crystals of pure and lanthanum doped potassium pentaborate (KB5) have been successfully grown by slow solvent evaporation technique. The grown crystals are confirmed by powder X-ray diffraction (PXRD). The mechanical strengths of the pure and doped crystals were found out using Vicker's micro hardness tests. The Second Harmonic Generation (SHG) of the crystals are confirmed by Nd:YAG pulsed laser employing Kurtz powder technique. The photoconductive studies reveal the negative photoconductive nature of the grown crystals.Keywords

Single crystals of pure and Lanthanum doped L- arginine acetate (LAA) were grown successfully by slow evaporation technique. The grown crystals were confirmed by X-ray powder diffraction studies. The pure and doped crystals were characterized by Fourier Transform Infrared (FT-IR) and UV-Vis-NIR studies. It was found that the optical properties were enhanced by the incorporation of the dopant. Nonlinear optical studies reveal that the dopant has increased the efficiency of the LAA crystal.Keywords
