Abstract

Amino acids (L-alanine, L- valine , L-histidine) doped Triglycine sulphate(TGS) crystals were grown by solution growth technique. Slow cooling as well as slow evaporation methods were employed to grow these crystals, the concentration of dopants in the mother solution was varied from 0.1 mole% to 10 mole % .The solubility data for all dopant concentrations were determined. The variation in pH and the corresponding habit modification of the grown crystals were characterized with UV - VIS, FT-IR and SHG trace elements and dielectric studies reveal slight distortion of lattice parameter for the heavily doped TGS crystals. The dopants increase the hardness value of the material, which also depends on the concentration of the dopants. Amino acids doping improved the NLO properties. The detailed results on the spectral parameters, habit modifications and constant values will be presented.
