Popis: Phosphate doped bis-urea oxalic acid (PBUO) crystals were grown using the aqueous solution by slow evaporation technique. Single crystal XRD study indicates that the sample crystallizes in monoclinic structure. The mechanical parameters like hardness, yield strength and stiffness constant of the crystal were determined by using the Vickers hardness tester. UV-visible spectral studies were done to determine the various linear optical parameters. Second harmonic generation (SHG) efficiency was measured for the grown crystal of PBUO to understand the nonlinear optical activity. TG/DTA analysis shows that the PBUO crystal is thermally stable upto 170 °C. Energy dispersive X-ray analysis (EDAX) was carried out by recording the EDAX spectrum of the grown crystal to identify elements in the sample. The grown PBUO crystals were also characterized by FTIR, SEM, PL, LDT and impedance studies.
