ABSTRACT: Bis L-alanine Triethanol amine (BLATEA) salt was synthesized by solution method and it was
subjected to solubility studies. Using the solubility data, the saturated solution of the synthesized
salt was prepared and single crystals of Bis L-alanine Triethanol amine (BLATEA) were grown
from aqueous solution by slow evaporation technique. X-ray diffraction (XRD) study was carried
out to confirm the crystal structure. FTIR study reveals the functional groups of the sample.
UV-Visible transmittance and absorption spectra were recorded for the sample to analyze the
transparency of the grown crystal. Vickers micro hardness values were measured for the sample
and from the microhardness study it is observed that BLATEA crystal is a soft material. SHG
generation study was carried out to confirm the NLO activity of grown sample and also BLATEA
crystal has been analyzed with dielectric measurements
