- Abstract
- The Pr3+ : D-1(2) -> (1)G(4) transition in silica-based oxide glasses, which emits a strong luminescence centered at about 1530 nm with full-width at half-maximum wider than 200 nm, may reserve potential practicality owing to its fairly long fluorescence lifetime of similar to 270 mu s corresponding to theoretical quantum efficiency approaching unity and its emission wavelengths matching up to the optical communication window of silica transmission fiber. To minimize non-radiative energy transfers among the active ions, the host materials need doping concentration of Pr2O3 tantamount to not more than 0.01 mol%. Impact of ground state absorption to (F-3(3), F-3(4)) level on the emission is discussed and then efficient excitation schemes are proposed. (c) 2005 Elsevier B.V. All rights reserved.
