Investigation on the Mechanical, and third harmonic generation analyses of non-linear optical single crystal of 2-Phenyl benzimidazole
The slow evaporation solution growth technique is used to grow single crystals of 2-phenylbenzimidazole (2PBMZ). The crystal is belongs to the monoclinic system with space group C2/c, which is revealed through the single crystal XRD. The cut-off wavelength and optical band gap energy of the 2PBMZ crystal were observed at 568 nm and 1.96 eV respectively. The Vickers (Hv) hardness number, yield strength and stiffness constant are calculated, which is found to increase with the applied load. The Z-scan technique with He–Ne laser (632.8 nm) has used to study the third order nonlinear optical property of 2PBMZ crystal.
