Solution growth and studies of undoped and lithium nitrate added glycine sodium nitrate single crystals

D. Dooslin Mary, M. Mary Freed

Abstract

Solution growth by slow evaporation method has been employed to grow semi-organic nonlinear optical crystals of pure and lithium nitrate doped glycine sodium nitrate (GSN). The grown crystals were subjected by single crystal and powder X- ray diffraction techniques to identify the crystal structure and diffraction planes. Fourier Transform Infrared (FTIR) spectra were recorded to identify the functional groups of the samples. Ultra Violet (UV)-visible spectral studies for the grown samples were carried out and analyzed. The investigations indicate the inclusion of the dopant into the lattice of GSN and enhancement of optical properties due to the incorporation of the dopant LiNO3 into the lattice of GSN. Second harmonic generation (SHG) efficiency was measured by Kurtz-Perry technique. The obtained results from various studies were discussed.
