Structure, optical, thermal, SHG & photoluminescence studies of L-Serine cadmium chloride single crystals

Abstract

Novel semi organic nonlinear optical single crystal of l-Serine Cadmium Chloride monohydrate has been synthesized by conventional slow evaporation method. The single crystal XRD have been employed to describe the crystal structure, space group, bond lengths, bond angles and co ordinates of hydrogen bond. The metal organic complexion between l-Serine and Cadmium chloride is taking place through oxygen atom of l-Serine. The lattice parameters obtained from PXRD technique have been found in good agreement with those obtained from SXRD. Williamson-Hall method has been used to determine the lattice strain of the grown crystal. The investigations of intermolecular interactions in LSCC crystal lattice are carried out by Hirshfeld surface analysis. The FTIR spectrum is utilized to determine the possible functional groups present in the crystal. The investigations on optical qualities of the crystal are carried out by incorporating UV–Visible and photoluminescence spectrum. The behaviour of refractive index below energy gap is carried out by Wemple – DiDomenico single oscillator model analysis. The thermal stability along with the decomposition temperature of the synthesized crystal is ascertained by thermogravimetric analysis. The kinetic and thermodynamic parameters of LSCC crystal have been calculated from C-R plot. Photoluminescence spectrum of the synthesized crystal was recorded by using an excitation wavelength of 320 nm. It suggested the suitability of the synthesized material as green laser diode. The SHG efficiency of LSCC crystal is clarified through the Kurtz-Perry technique.
