Abstract: | The optical properties of Tm3+ in a fluorophosphate glass are reported. Oscillator strengths and Ωλ parameters for Tm3+ were calculated. Energy transfer between Ce3+ → Tm3+, Tm3+ → Eu3+ and Tm3+ → Tb3+ were measured at room temperature and interpreted using the Yokota and Tanimoto scheme. Fluorescence decay results seem to support the hypothesis of a diffusion-limited relaxation. The effects of Tb3+ and especially Ce3+ on the fluorescence of Tm3+ ion point out the interest of these dopants for obtaining a better emission of Tm3+ at 450 nm. |
