Design of an efficient solution grown semiorganic NLO crystal for short wavelength generation: Bis(L-Threonine) magnesium (II) monohydrate

An eccentric lucid nonlinear semiorganic optical material Bis(L-Threonine) magnesium (II) monohydrate [BLTM], were lucratively grown by a conventional solution growth method at room temperature for the first time. The cell parameters were estimated from single crystal X-ray diffraction analysis. Spectroscopic studies have been carried out for analyzing the presence of functional groups. UV spectrum shows the subsistence of wide transparency window suitable for optoelectronic applications. The fluorescence emission spectrum of the title crystal shows green emission. The decomposition and thermal stability of the compound were explored by TGA-DSC studies. Second harmonic generation (SHG) conversion efficiency was estimated using Kurtz and Perry powder method.
