Studies on the structural, thermal, optical and nonlinear optical characteristics of a novel organic glycine doped l-arginine adipate crystals

Abstract

Pristine and glycine doped l-arginine adipate (LAA) crystal, is a novel NLO materials were proficiently grownup by a simple slow evaporation way at ambient environment. The lattice parameters and crystalline nature for the as-synthesized crystals have approved in powder X-ray diffraction (XRD) statistics, while exhibited the as-grown crystals have monoclinic crystal system through precise space group. FT-IR and 1H NMR spectroscopy designate that the plausible assortment kinds of molecular vibrations/configuration of as-grown crystals. Linear optical effects were originating via UV–Vis absorption spectral probe, and the cut-of wavelength has ~ 205 and 208 nm for LAA and GLAA crystals exclusively. The UV–Vis optical transmission inquiry exposed that the glycine doped LAA (GLAA) crystal had precise high optical transparency into visible-region and the virtual bandgap were calculated. Photoluminescence (PL) belongings tested for the grown LAA and GLAA crystals were detected fluorescence band emission at ~ 400–650 nm. Auxiliary, the developed crystals have scrutinized for thermal assets by TGA/DTA study and the results are inferred. Besides, the NLO belongings by Kurtz’s and Perry technique which screening on the grown GLAA crystal was conversed to indorse the increases of SHG efficacy.
