摘要

In the present work, a good transparent semi-organic brucinium bromide hydrate (BBH) single crystal was grown from the saturated solution by slow evaporation method. The single crystal XRD study reveals that, BBH crystallize in Triclinic crystal system with non-centrosymmetric space group P1. Presences of chemical elements such as Carbon, Hydrogen and Nitrogen are C = 38.79%, H = 44.10% and N = 3.48% respectively. The morphological study concludes that, the growth rate along 'c' direction is more expeditious than that of a & b. The UV-Visible spectrum confirms the good transparency of the crystal and diverse optical parameters such as cut-off wavelength, band gap, UV-resonance energy and refractive index values were calculated and relation between the different optical parameters were also discussed in detail. Chemical bonding nature of BBH crystal was identified with the aid of optical electro-negativity value. The Urbach energy value was found to be 0.1238 eV. LDT value of BBH crystal was found to be 6.43 GW/cm(2) and it is compared with other standard materials such as KTP, KDP and Urea. To find the suitability of crystal in the field of nonlinear optical application, the second harmonic generation value was determined using Kurtz-Perry powder technique. The spectroscopic investigations were done by vibrational analysis in order to identify the different functional groups in BBH compound. The value of piezo-electric charge co-efficient (d(33)) was quantified by PM-300 piezometer. Fluorescence spectral study provides the knowledge about electron excitation and also life time of the molecules. Title crystal does not contain any internal structural grain boundaries which are confirmed by HRXRD analysis. (C) 2018 Elsevier B.V. All rights reserved.
