Abstract

This paper reports the synthesis and characterization of three new Gd(III) complexes with Succinimide, Nhydroxysuccinimide and N hydroxyphtalimide. Several investigation techniques were used for characterization of the new prepared complexes, as follows: Elemental chemical analysis, FT-IR, TG / DTA analysis, Powder X-ray diffraction, SEM and fluorescence spectroscopy. Data obtained through analysis revealed the formation of the Gd complexes with above mentioned ligands at 1:3, metal to ligand (M:L) molar ratio. The PL spectra revealed the fluorescent emission of the Gd - Nhydroxysuccinimide complex in the blue region of the visible spectrum, the peak emission being recorded at 423 nm which makes it particularly interesting for applications in optoelectronics and medical imaging..
