Resumen

By means of UV-VIS absorption measurements to zinc-tellurite glasses doped with Yb, Tm and Er, we obtained the band gaps, Urbach energies, the polarizability values and the Judd-Ofelt parameters, which indicated an increase in the structural disorder in the host matrix. © Optica Publishing Group 2022 The Authors.
