摘要：
We have prepared Er3+/Yb3+ co-doped transparent phosphate glass ceramics by the high-temperature melting technique, and demonstrated the influence of energy acceptors Ce3+ ions on the up-conversion and 1.54 mu m emission properties of Er. The energy transfer mechanism is discussed based on the energy matching and the energy level structure. The phonon-assisted energy transfer between Er3+ and Ce3+ favors population feeding from the I-4(11/2) to the I-4(13/2) level, and therefore drastically decreases the up-conversion emission intensity of Er3+. Meanwhile, 1.54 mu m fluorescence enhances greatly with the introduction of Ce3+ ions at the proper concentration. (C) 2009 Elsevier B.V. All rights reserved.
