Study of the second harmonic emission of glycine-sodium nitrate crystals at different pH

Abstract

This work shows an optical and structural study of glycine sodium nitrate crystals. This study was supported with the respective X ray diffracttion and Second-Harmonic Generation signal detection by using a little variant to the Kurtz- Perry method. The goal of this work is to obtain the right pH that modifies the charge of glycine sodium nitrate system in order to obtain the best second harmonic emission. Furthermore with the change on the charge on the aminoacid, it is observed how it modifies the optical properties in the glycine sodium nitrate complex

Comparative Study of Nonlinear Semi-Organic Crystals: Glycine Sodium Nitrate

“…The Raman spectra is shown in figure 11 whereas FTIR spectras are shown in figure 12-13 for both crystals recorded by Perkin Elmer Spectrum GX from 400-4000 cm -1 . Small shifts in wavenumber were observed in Raman spectra when matched with reported data [4,15]. …”

“…NLO effect is interaction of an electromagnetic field of high intensity laser with a material [1][2][3][4]. NLO materials have applications in many fields like laser technology, optical communication, and electro optics.…”

“…NLO materials have applications in many fields like laser technology, optical communication, and electro optics. Dealing with organic materials like amino acid provides one the advantage of (1) fine-tune chemical structure [4] (2) zwitterionic nature of molecule which favors crystal hardness (3) absence of strongly conjugated bonds, leading to wide transparency window in UV-Visible spectrum [5][6][7][8]. In the present research work, Glycine sodium nitrate crystal were grown with molar ratio of Glycine: Sodium nitrate (2:1) and (3:1).…”

Comparative Study of Nonlinear Semi-Organic Crystals: Glycine Sodium Nitrate

“…Over the last few years, researchers are extensively investigating the amino acid based semiorganic crystals because of their nonlinear optical (NLO) property. NLO effect is interaction of an electromagnetic field of high intensity laser with a material [1][2][3][4]. NLO materials have applications in many fields like laser technology, optical communication, and electro optics.…”
