Growth and characterization of organic material 2-bromobenzyl alcohol single crystal by vertical Bridgman technique

Abstract

The organic material 2-bromobenzyl alcohol (C7H7BrO) single crystal was grown by using vertical Bridgman technique. The lattice parameters of the 2-bromobenzyl alcohol crystal were determined by single-crystal X-ray diffraction technique. The Fourier Transform Infrared spectroscopy is used to identify the functional groups of the grown 2-bromobenzyl alcohol. Thermal analyses were carried out to analyze the melting and decomposition points of the grown crystal. The UV–Vis–NIR and Fluorescence studies assessed the optical properties of the grown crystals. The second-harmonic generation study analyzed non-linear properties. The laser damage threshold value for the grown 2-bromobenzyl alcohol single crystal was measured by using Q-switched Nd:YAG laser. The photoconductivity measurements of the grown crystal were estimated by KEITHLEY 6487 instrument. The dielectric permittivity was analyzed at various temperatures with different frequencies from 1 to 5 MHz. The mechanical strength of the grown crystal was analyzed by using Vickers microhardness analysis.
