Synthesis, Structural, Spectral, Optical and Mechanical Study of Benzimidazolium Phthalate crystals for NLO Applications

Organic nonlinear crystal benzimidazolium phthalate have been grown by slow evaporation solution growth technique. The crystal belongs to orthorhombic crystal system space group P21. The functional groups present in the crystal were identified by FT-IR spectrum. The UV-Visible spectrum study reveals that the crystal has excellent transmittance the cut-off region being 205 nm. The photoluminescence spectrum shows violet emission. The chromaticity coordinates are calculated from the emission spectra and the emission intensity of the grown crystal is characterized through color chromaticity diagram. Dielectric studies find a way for the crystal to be used for opto electronic devices. Vicker’s hardness test shows its mechanical behavior. The NLO property was confirmed by green emission in SHG test. Figure 1: As grown crystal of BPA by slow evaporation method.
