Growth and Characterization of L-glutamic Acid Hydro Chloro Bromide,A New Nonlinear Optical Material

摘要

The influence of mixed acids in the growth and characteristic properties of a nonlinear optical material L-glutamic acid hydro chloro bromide abbreviated as LGAHCB was examined. Single crystal X-ray diffraction analysis was used to calculate the lattice parameters of the crystals. Fourier transform infrared spectroscopies were performed to study the molecular vibrations of the grown crystal. The optical transmission spectrum shows very low absorption in the entire visible region. The powder second harmonic generation efficiency of LGAHCB is 1.5 times efficient as potassium dihydrogen phosphate (KDP).
