In this paper, we report on the observation of enhanced 2.7 mum midinfrared emission under 800 nm excitation in a Nd{sup 3+}/Er{sup 3+} codoped tellurite glass. It is also found that the green upconversion emissions from Er{sup 3+} are effectively restricted, meanwhile the {sup 4}I{sub 13/2} level of Er{sup 3+} is depopulated in the Nd{sup 3+}/Er{sup 3+} codoped tellurite glass. These results suggest that the midinfrared emission can be achieved in the oxyfluoride glasses and that codoping with Nd{sup 3+} can greatly improve the midinfrared emission performance.
