Benzimidazolium Gallate: Organic Crystal for Photonic and Optoelectronic Applications

Solvent evaporation was used to create a novel organic optical crystal of Benzimidazolium gallate (BGA). The size of unit cells was determined using XRD analysis. FT-IR spectrum analysis revealed chemical bonds' vibrational behavior and their functional groups’ existence. Optical transparency and optical bandgap (3.66 eV) were observed by the UV-Visible-near Infrared spectral analysis. TG/DSC curves show that decomposition is exhibited at 215 0C. Dielectric experiments on the BGA crystal were performed at ambient temperature. HR-SEM analysis shows the crystal's nature and surface shape. The Z-scan process explored the BGA crystal's nonlinearity, and the crystal is suitable for photonic, optoelectronic, and optical-limiting applications.
