Investigation on Pure and L-lysine Doped (Tri) Glycine Barium Chloride (TGBC) Single Crystal for Nonlinear Optical Applications

Single crystals of pure and L-lysine doped (tri) glycine barium chloride (TGBC) were grown by slow solvent evaporation technique with the vision to improve the physicochemical properties of the sample. Single crystal X-ray diffraction analysis of both pure and doped samples was carried out and the results are compared. Optical absorption and FTIR spectroscopic studies are performed to identify the UV cut-off wavelength range and the presence of various functional groups in the grown crystals. The thermo gravimetric (TG) analysis of L-lysine doped TGBC indicates a marginal increase in the thermal stability of the crystals. The SHG efficiency of pure and doped TGBC was discussed.
