A Study Of Growth And Characteristics Of Metal Salt Like Manganese Sulphate [MnSO4] Doped In L Threonine Amino Acid Single Crystal For NLO Application

Abstract

L threonine is one of the amino acids exhibiting NLO properties. Study of Manganese sulfate doped in L threonine has been investigated. Pure L threonine and doped with MnSO4 were grown by slow evaporation method at room temperature. Good quality & transparent crystals were obtained in a month. . The Powder XRD study shows the tetragonal structure with lattice parameter a = b = 7.506 Å and c = 7.555 Å. Doping of MnSO4 in L-threonine crystal was confirmed by FT–IR spectroscopy. NLO properties & hardness testing was executed for grown crystal. Poor SHG efficiency of grown crystal was observed as compared to KDP
