IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishWe report on the fabrication of three tellurite glass compositions co-doped with Yb3+/Er3+, Yb3+/Tm3+ and Yb3+/Pr3+, respectively. The thermal properties of the glasses are presented and discussed. We investigated the intense upconversion photoluminescence generated at visible wavelengths by the samples when excited by a commercial infrared (IR) laser operating at 978 nm. With the aim to exploit this emission for biomedical, optical sensing or display applications, we discuss the fabrication of a microstructured fibre whose core consists in three concentric rings made of the three active glasses mentioned above. Morphological and optical characterisations of the optical fibre are presented and preliminary conclusions on the prospect of such device are also drawn.

| Abstract: | We report on the fabrication of three tellurite glass compositions co-doped with Yb3+/Er3+, Yb3+/...Tm3+ and Yb3+/Pr3+, respectively. The thermal properties of the glasses are presented and discussed. We investigated the intense upconversion photoluminescence generated at visible wavelengths by the samples when excited by a commercial infrared (IR) laser operating at 978 nm. With the aim to exploit this emission for biomedical, optical sensing or display applications, we discuss the fabrication of a microstructured fibre whose core consists in three concentric rings made of the three active glasses mentioned above. Morphological and optical characterisations of the optical fibre are presented and preliminary conclusions on the prospect of such device are also drawn. | |
