Abstract :

A new layered noncentrosymmetric (NCS) bismuth oxyfluoride-nitrate was synthesized by a hydrothermal reaction. The crystal structure was determined by powder and single-crystal X-ray diffraction. The material crystallizes in an NCS trigonal space group, R3 (No. 146). The constituting [Bi6O7F3]+ cationic layer contain H2O and nitrate anion makes a charge balance. The powder second harmonic generation (SHG) measurements indicate the title compound is phase-matchable (Type I) and exhibits a strong SHG efficiency of about 90 times that of �?±-SiO2. Detailed structural examination suggests that the Ï�?-conjugate system of nitrate anion directly influence the nonlinear optical (NLO) properties of the material. Infrared and UVâ�?�?vis diffuseâ�?�?reflectance spectroscopy, energy dispersive X-ray spectroscopy (EDS), thermogravimetric analysis (TGA), and local dipole moment calculations are also presented.
