    • Abstract

       

      L-threonine ammonium bromide (LTAB) is a significant nonlinear optical (NLO) material. The crystal has been grown by the slow evaporation technique (SET). Ammonium bromide has properties, which are that of chiral molecules and zwitterions environmental benefits due to advance NLO properties of LTAB. L-threonine-doped ammonium bromide crystals are grown using SET at ambient temperature. In this study, the unit cell factors are derived from X-ray diffraction (XRD) studies. The powder XRD spectra suggests the formation of orthorhombic crystal system. Fourier transform infrared spectroscopy (FTIR) analysis depicts the different functional groups offered in the grown crystals. The study of optical transmittance was done by crystals utilizing ultraviolet, visible, spectral analytical methods. Further, the minimum cutoff wavelength of the grown crystal has been recognized as 220 nm. The overall result of the second harmonic generation (SHG) efficiency is depicted higher and nearly around LTAB obtained crystal which is greater than potassium dihydrogen phosphate (KDP). It proves the potential application of LTAB crystal in optoelectronic industries.
