Study on the Energy Transfer Process of Tb3+, Ce3+ Ions Doped Phosphate Glasses
View through CrossRef
We have systematically studied the spectral properties of Ce3+, Tb3+ ions in different glass hosts[1]. In this paper the concentration effect and energy transfer process between Tb3+ and Ce3+ ions were reported. A series of glasses with the following doping concentration were prepared. (1) Tb3+ — 2, 4, 8, 12, 16 wt%. (2) Ce3+ — 1, 3, 5 wt%, 17 mol%. (3) 8 wt% Tb, Ce3+ — 1, 3, 5 wt% The emission and excitation spectra of these glasses were obtained using Hitachi Model 650-60 fluorescence spectrophotometer. Decay times of the 5D4 - 7F5 transition (542nm, 548nm) at the different Tb3+ concentrations were measured using an KrF excimer laser with pulse duration 10ns as the exciting light source.
