| Abstract | Luminescence properties of oxyapatite co-doped Ca8, 9 Tb1 Eu0, 1 (PO4)6 O0.45[]1,55 with europium and terbium was studied, a comparative study of oxyapatites doped with only Eu 3+ , Tb 3+ or both of these two ions, was conducted under laser excitations lines at 488 nm, 457.9 nm and 337.1 nm. Using a characteristic transition in the Europium 5 D0 ----7 F0, 1, 2 and Terbium 5 D4 ----7 F5, 4, 3 spectra at 77 K. A significant energy transfer from Tb 3+ to Eu 3+ was evidenced for the co-doped oxyapatite. Such energy transfer seems to occur via different mechanisms which involve particularly high levels of the ion Tb 3 + ( 5 D3 or above). |
