The ultraviolet to near-infrared spectral modification in Ce3+and Yb3+codoped phosphate glasses was realized through the energy transfer from Ce3+to Yb3+. The absorption spectra, fluorescence excitation and emission spectra, luminescence decay curves, and time-resolved emission spectra were measured and analyzed. The energy transfer efficiency and concentration quenching efficiency were calculated based on the decay curves of Ce3+340 nm emission and Yb3+976 nm emission. The calculated and experimental NIR emission intensities on the Yb3+concentrations were compared and discussed. Copyright © 2010 Published by Elsevier B.V. All rights reserved.
