Fluorescence and Energy Transfer in Er³⁺/ Nd³⁺ Co-Doped Oxyfluoride Tellurite Glass

Abstract:

Er3+/Nd3+ co-doped oxyfluoride tellurite glass was prepared successfully by the conventional melting method. Luminescent properties of Er3+/Nd3+ co-doped oxyfluoride tellurite glass were studied in the NIR spectral range. There existed strong absorption peaks of Nd³⁺ ions at 580 nm, 743 nm, 800 nm and 874 nm and obvious absorption peaks of Er³⁺ ions at 580 nm, 743 nm, 800 nm and 874 nm. Er 3+ /Nd 3+ co-doped glass performed excellent fluorescence properties at 1.53 μm and 1.06 μm. There existed energy transfer between Nd3+ ions and Er3+ ions, that is 4I9/2 (Er 3+ ) + 4I9/2 (Nd3+) → 4I15/2 (Er3+) + 4F5/2 (Nd3+). Owing to the energy transfer from Er3+ ions to Nd3+ ions, multi-phonon relaxation or up-conversion radiations, emission intenisty of Er3+/ Nd3+ co-doped glass was weaker than that of Er3+ single-doped glass at 1.53 μm.
