Synthesis, growth and characterization of L‐histidinium acetate dihydrate single crystals

Abstract

L-histidinium acetate dihydrate {abbreviated as LHAc; [C 6 , a new nonlinear optical (NLO) material has been grown from aqueous solution. The grown crystals were subjected to X-ray diffraction, Fourier transform infrared (FTIR) and FT-Raman analyses. Thermal studies have been carried out for its thermal stability. Optical behaviour such as UV-Vis-NIR spectrum and second harmonic generation (SHG) were also investigated. Its SHG efficiency was found as d eff = 2.2 d eff (KDP).
