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: Lanthanum, potassium pentaborate, crystal growth.
