title: Crystal growth and spectroscopic characterization of Aloevera amino acid added lithium sulfate monohydrate: a non-linear optical crystal.
abstract: Non-linear optical crystals of lithium sulfate monohydrate added with Aloevera amino acid were grown successfully by slow evaporation technique moderately at low cost. Initially the Aloevera amino acid extract was prepared from the 3 years old plant leaves and the amino acids present in that were identified by high performance liquid chromatography. The grown crystal was clear, transparent and they attained the size about 1.3×0.8×0.6 cm(3) within a time span of 20-25 days. The crystal was subjected to Fourier Transform Infrared Spectroscopy, UV-Vis-NIR, thermal and mechanical studies. Proton nuclear magnetic resonance, thin layer chromatography and colorimetric estimation techniques are carried out to confirm and identify the amino acid in the grown crystal.
