Synthesis, growth and characterization of l‐alaninium oxalate ‐ a novel organic NLO crystal

Abstract

Nonlinear optical material of L-alaninium oxalate (LAO) has been synthesized and single crystals are grown by slow evaporation technique. The solubility data of LAO is determined in water. Single crystal X-ray diffraction study showed that LAO belongs to orthorhombic system with a non-centrosymmetric space-group P2 1 2 1 2 1 . The functional groups have been identified from FT-IR spectrum. The UV-Vis-NIR spectrum of LAO shows less optical absorption in the entire visible region. The second harmonic generation (SHG) in the material was estimated using Nd:YAG laser. The mechanical properties of the grown crystals are studied using Vickers microhardness tester. The AC and DC conductivity, and dielectric studies are also carried out and reported for the first time.

Characterization of pure and urea-doped γ-glycine single crystals grown by solution method

“…Most of the amino acids and their complexes are the family of organic and semi-organic nonlinear optical (NLO) materials that have potential applications in second harmonic generation (SHG), optical storage, optical communication, photonics, electro-optic modulation, optical parametric amplifiers, optical image processing, etc [1][2][3][4][5][6]. It is known that glycine, the simplest amino acid, exhibits in three different polymeric forms viz.…”

Optical Conductivity and Dielectric Response of an Organic Aminopyridine NLO Single Crystal

“…Then, generally, a redistribution of charges occurs and currents are induced. The ac conductivity of the samples was calculated using the formula [17]; σ ac = ε 0 ε r ωtanδ (5) where ω be the angular frequency (ω = 2πν). to 10 kHz and then increases with the increase of frequency.…”

Investigation on Optical, Electrical, Third Harmonic Generation and Hirshfeld Analysis Characteristics of Novel Organic 3‐Amino‐1H‐1,2,4‐Triazole 3,5‐Dinitrobenzoic Acid Monohydrate (3ATDM) Crystal for Nonlinear Optical (NLO) Applications

“…High-quality organic NLO crystals have a large NLO coefficient, low laser damage threshold power, and a large optical transmission combined with a shorter cut-off wavelength. [1,2] Organic NLO materials were functionalized appeal to a good deal of concentration due to its concern in the harmonic generation, switching other types of single processing devices materials, amplitude and phase modulation. [2][3][4] Organic NLO materials have a leading role in the fast-developing fields such as photonics and optoelectronics.…”
