Análisis Judd-Ofelt del sistema vítreo Teo2-Zno dopados con Re3+ (Re=Yb, Tm, Er).

The Judd-Ofelt analysis is essential because it indicates the influence of rare earth ion doping on the host matrix in which they are found. In the present work, the results of the optical characterization of zinc-tellurite glasses doped with Yb3+ are presented, varying the concentrations of Tm3+ and Er3+ by means of UVVIS absorption spectroscopy and refractive index measurements. From these results, the Judd-Ofelt parameters were obtained, which indicated a structural modification with the addition of rare earth ions in the tellurite glassy matrix, due to the rearrangement of the glassy structure and the breaking of Te-O bonds.
