Comprehensive studies on amino acid based organometallic L-threoninum cobalt (II) sulfate (LTCS) single crystal and its antibacterial and antifungal properties

Abstract

Highly transparent superior quality nonlinear single crystals of L-Threoninum Cobalt (II) Sulfate Heptahydrate were prepared by simple novel slow evaporation solution growth method. The space group, lattice parameters, crystal structure and crystalline nature of L-Threoninum Cobalt (II) Sulfate (LTCS) materials assessed through diffraction analysis (PXRD and SXRD). The optical behavior of LTCS crystals were checked via UV–Vis analysis and it confirms optical parameters often depend on photon energy with optical band gap Eg = 5.6 eV and LTCS material can be acceptable for optoelectronic devices. The hardness and work hardening coefficient of LTCS crystal were investigated using Vickers microhardness testing and the work hardening value 1.94 point out soft nature of the grown material. By use of Kurtz and Perry technique the nonlinear second harmonic generation (SHG) efficiency of prepared LTCS crystals was assessed. The LTCS material developed here is used to treat bacterial and fungal infections and is detected by an antimicrobial assay.
