Synthesis, structure and spectroscopic studies of europium complex with S(+)-mandelic acid

The Eu3+ complexes with S(+)-mandelic acid were synthesized in the form of powders by mixing aqueous solutions of EuCl3,S(+)-mandelic acid and NaOH in different molar ratios.The powders were characterized by elemental analysis,X-ray powder diffraction (XRPD) method,Fourier transform infrared (FTIR) and Raman spectroscopy,UV-vis reflectance and luminescence spectra as well as luminescence lifetime measurements.It was found that all studied powders of Eu3+ complexes with S(+)-mandelic acid were isostructural and crystalline and formed compounds with the formula Eu(Man)3(H2O)2.
