Growth and characterization of L‐histidine hydrochloride monohydrate single crystals

Abstract

Good optical quality single crystal of L-histidine hydrochloride monohydrate (LHC) a novel semi organic NLO material was grown by slow solvent evaporation technique. The crystal was characterized by X-ray diffractometry (XRD), Fourier Transform Infra-red (FTIR), UV-Vis-NIR, TGA, DTA, microhardness and solubility studies. The SHG efficiency is found to be higher than that of KDP crystal. The dielectric constant and dielectric loss of the crystal was studied as function of frequency and the results are discussed. Photoconductivity studies were also carried out which reveals the positive photoconducting properties of the sample.

Crystal Growth, Optical and Dielectric Properties of L-Histidine Hydrochloride Monohydrate Nonlinear Optical Single Crystals

“…The lattice parameter values of the grown crystals are a = 6.82 Å, b = 8.91 Å, c = 15.286 Å. The single crystal data are in good agreement with reported values [9].…”

Synthesis and Characterization of Pure and Doped L- Arginine Maleate Single Crystals

“…Of this second order NLO materials capable of high efficiency in frequency conversion of infrared or visible laser radiation to visible or ultraviolet wavelengths. Therefore presently there is a need to produce high efficiency NLO materials [1][2][3][4]. KDP group of materials are widely used in frequency conversion due to their modest nonlinearities [5].…”

Synthesis, Crystal Growth, Structural, Optical, Thermal and Mechanical Properties of Semiorganic Nonlinear Optical Material: L-Cystine Dihydrochloride

“…Amino acids are interesting materials for NLO application as they contain a proton donor carboxyl acid (-COO) group and the proton acceptor amino (-NH 2 ) group in them. A series of semi-organic compounds such as l-histidinium hydrogen malate 5 , L-arginine diphosphate 6 , L-Lysine monohydrochloride dihydrate 7 , L-histidine hydrochloride monohydrate 8 and L-glutamic acid hydrochloride 9 have been reported with moderately high mechanical and chemical stability. Our laboratory is engaged in finding new materials for NLO applications and some of these were reported recently [10][11][12][13] .…”
