Resumen
The tellurite fibers based on glasses with the composition TeO 2-WO3-Nb2O5-Na2O-Al 2O3-Er2O3-Yb2O 3 were fabricated by the rod-in-tube technique using a Heathway drawing tower. The upconversion luminescence of Er3+/Yb3+ codoped tellurite glass fibers under 980 nm excitation were investigated. The Er3+/Yb3+co-doped tellurite fibers show an efficient up-conversion process in comparison with the Er3+-doped tellurite fibers. The pump power dependent intensities were discussed, which showed that two photons are involved in the upconversion process. © 2012 Elsevier B.V. All rights reserved.
