The upconversion luminescence properties of Yb 3+ /Tm 3+ -codoped oxyfluoride tellurite glasses under 980 nm excitation are investigated experimentally. The intense blue and relatively weak red emissions centered at 475 and 649 nm corresponding to the transitions 1 G 4 β†’ 3 H 6 and 1 G 4 β†’ 3 H 4 of T
