Title: Analysis of upconversion luminescence in Yb<sup>3+</sup>/Er<sup>3+</sup>co-doped tellurite optical fiber
Abstract: In the paper the analysis of upconversion luminescence in Yb<sup>3+</sup>/Er<sup>3+</sup> co-doped tellurite glass and optical fiber has been investigated. Upconversion luminescence at 525 nm, 546 nm, 651 nm corresponding to the Er<sup>3+</sup>: <sup>2</sup>H<sub>11/2</sub>→<sup>4</sup>I<sub>15/2</sub>, <sup>4</sup>S<sub>3/2</sub>→<sup>4</sup>I<sub>15/2</sub>, (<sup>4</sup>F<sub>9/2</sub>→<sup>4</sup>I<sub>15/2</sub>) transitions, respectively was obtained as a result of energy transfer between Yb<sup>3+</sup> and Er<sup>3+</sup> ions. Developed tellurite glass characterized by highest intensity of upconversion luminescence (0.5mol% Yb<sub>2</sub>O<sub>3</sub>/0.1mol% Er<sub>2</sub>O<sub>3</sub>) was used as core of optical fiber. The analysis of influence of Yb<sup>3+</sup>/Er<sup>3+</sup> co-doped tellurite optical fiber length on upconversion emission spectra was examinated.
