Growth, mechanical, dielectric and photoconducting properties of bisglycine hydrobromide NLO single crystal

Single crystals of Bisglycine Hydrobromide (BGHB) have been grown by slow evaporation technique. The unit cell dimensions and morphology of the grown crystals are confirmed by single crystal X-ray diffraction. The grown crystals were also subjected to microhardness. The microhardness studies indicate that the Vickers hardness number of the crystal decrease with the increase in applied load. Dielectric constant and dielectric loss measurements were carried out at different temperatures and frequencies. The photoconductivity studies confirm that the title compound has negative photoconductivity nature.
