Abstract
A series of doping complexes Sm1-xMx (TTA)3 phen (M denotes Gd3+ or Y3+, TTA stands for 2-thenoyltrifluoroacetone, phen denotes 1, 10-phenanthroline, x is the mole fraction of doping elements) as light conversion agent are synthesized by chemical precipitation method, and the characteristics of the compounds are performed using infra-red spectrum (IR), UV-visible absorption and fluorescence spectroscopy. The results indicate that the structure of Sm1-xMx (TTA)3 phen are similar to Sm (TTA)3 phen, and the characteristic UV absorption peaks of Sm1-xMx (TTA)3phen are depended on organic ligands. Photoluminescence measurements indicate that the complexes emit strong luminescence, which is determined by the transitions of center samarium ion under UV radiation. The strongest luminescence of Sm0.5Y0.5 (TTA)3 phen is at 647 nm, up to 9.5 × 106 cps. The luminescence of Sm1-xMx (TTA)3 was enhanced with the addition of sensitized elements, Y3+ is better than Gd3+.
