Abstract
Abstract The ternary Sm(III) complex with the salicylic acid (HSal) and o -phenanthroline (Phen) has been prepared. The photoluminescence intensity of the complex Sm(Sal) 3 (Phen) is enhanced by more than two hundred times with respect to that of the binary complex Sm(Sal) 3 (H 2 O) 2 . It is confirmed by Sm(III) content titration and the spectra of IR, UV–vis and fluorescence that the second ligand, Phen, also coordinates with the Sm 3+ ion. The second ligand Phen shows enhancement effect on the fluorescence of the complex. These observations are discussed in detail and the results are rationalized.
