Growth and characterisation of L-tyrosine-doped TGS crystals

Single crystals of L-tyrosine-doped triglycine sulphate (LTTGS) were grown by low-temperature solution method. Morphological changes were observed on the grown crystals. Crystalline quality and cell parameter values were dete rmined using rocking curve and powder X-ray diffraction analysis. The prese nce of r-tyrosine in LTTGS was estimated qualitatively by FTIR analysis. Mi crohardness studies carried out using Leitz Weitzler hardness tester at roo m temperature showed a decrease due to doping. Domain studies on b-cut plat es were observed using scanning electron microscopy. (C) 2000 Elsevier Scie nce B.V. All rights reserved.
