In this paper, we report on the observation of enhanced 2.7  µm midinfrared emission under 800 nm excitation in a Nd3+/Er3+ codoped tellurite glass. It is also found that the green upconversion emissions from Er3+ are effectively restricted, meanwhile the 4I13/2 level of Er3+ is depopulated in the Nd3+/Er3+ codoped tellurite glass. These results suggest that the midinfrared emission can be achieved in the oxyfluoride glasses and that codoping with Nd3+ can greatly improve the midinfrared emission performance. ©2009 American Institute of Physics
