摘要 The Eu^3＋ 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 Eu^3＋ complexes with S（＋）-mandelic acid were isostructural and crystalline and formed compounds with the formula Eu（Man）3（H2O）2.
