Studies on structural, optical and dielectric properties of novel NLO crystal L- glutamic acid hydroiodide

The method of Slow Evaporation (SlEv) is carried out to create a single crystal of L-glutamic acid hydroiodide, a novel semi-organic nonlinear optical (NLO) substance with excellent optical quality. Both functional and optical characterization were applied to the crystal structure. The sample's lattice characteristics were ascertained using the powder X-ray diffraction (XRD) measurements. The sample's UV-Vis-NIR spectrum analysis projects that the crystal is optically transparent in the visible and infrared (IR) spectrums. The presence of several functional groups in the sample was verified by FT-IR spectroscopy. At various temperatures, the crystal's dielectric characteristics were scrutinized as a function of frequency. The material is a positive photoconductor, according to photoconductivity experiments. Using a Nd:YAG laser and the Kurtz-Perry method, the crystal's second harmonic generation (SHG) effectiveness was shown and contrasted with that of a potassium dihydrogen phosphate (KDP) crystal.
