title: Growth, spectroscopy, dielectric and nonlinear optical studies of novel organic NLO crystal: L-Threonine formate.
abstract: An efficient, novel, organic nonlinear optical (NLO) crystal of L-threonine formate (LTF), with dimensions 15mm×9mm×3mm was grown by slow evaporation technique at ambient temperature. Solubility and metastable zone-width measurements have been carried out for LTF sample. The metastable zone-width studies have been carried out for different cooling rates. The grown crystals were subjected to single crystal X-ray diffraction to determine the unit cell dimensions and morphology. The formation of the new crystal has been confirmed by NMR and mass spectroscopic analysis. The dielectric constant and dielectric loss measurements of the as grown crystal at different temperatures and frequencies of the applied field are measured and reported. The existence of SHG conversion efficiency was measured using an Nd:YAG laser (1064nm).
