Abstract

Seven complexes of rare earth (

=Sm

Dy)and Tb

doped with

(La

)with phenoxyacetic acid ( HPOA ) and 1

10-phenanthroline were synthesized. Their elemental analysis and rare earth complexometic titration were determined

the results showed that the chemical formulas were SmL

L'=phen).IR spectra

UV spectra and fluorescence spectra were studied. The results indicated that the rare earth ions are bounded with the oxygen atoms of phenoxyacetic acid and phenoxy

and with the N atoms of 1

10-phenanthroline. Fluorescence spectra of the complexes are determined at room temperature

the terbium complex showed that there is a characteristic excitation peak

which is a wide band from 280 to 380 nm

and a maximum peak at 331 nm. For europium complex

the band is from 280 to 370 nm and with a maximum peak at 348 nm.For dysprosium and samarium complexes

the bands are from 290 to 350 nm and 320 to 370 nm

the maximum peaks at 333 nm and 354 nm

respectively.The characteristic excitation peaks are assigned to the ligands metal energy transfer band. So

331

348

333 and 354 nm were chosen as excitation wavelength to measure the fluorescence spectra of terbium

europium

dysprosium and samarium complexes

respectively. The intensity of terbium complex is the strongest

europium complex is second and samarium is the weakest.It was shown that the lowest excitation state energy level of Tb

ion matches well with the triplet state energy of the ligand phenoxyacetic acid and phenanthroline each other

the absorbing energy of the ligands may effectively transferred to Tb

ion. The fluorescence intensity of terbium complex is enhanced after doping Y

ion.
