Abstract
Optically transparent Er<sup>3+</sup>/Tm<sup>3+</sup>/Yb<sup>3+</sup> tri-doped oxyfluoride tellurite based nano-crystallized glass ceramics with the batching composition of 73TeO<sub>2</sub>-15ZnO-7ZnF<sub>2</sub>-3YF<sub>3</sub>-1.5YbF<sub>3</sub>-0.3ErF<sub>3</sub>-0.2TmF<sub>3</sub> (mol%) is prepared by a conventional melting quenching and the subsequent heat treatment processes. The sizes of grown nano-crystals in glass matrix appear to be smaller than 100 nm from the scanning electron microscope measurement. Visible up-conversion luminescence of the as melted glass and glass ceramics is investigated. The three-color up-conversion luminescence intensities by 980-nm pumping are increased significantly due to the heat treatment, and the blue intensity increases with a higher magnitude than other wavelengths after heat treatment.
