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
