Influence of P₂O₅ and Al₂O₃ content on the structure of erbium-doped borosilicate glasses and on their physical, thermal, optical and luminescence properties
Abstract
The effect of P<sub>2</sub>O<sub>5</sub> and/or Al<sub>2</sub>O<sub>3</sub> addition in Er-doped borosilicate glasses on the physical, thermal,optical, and luminescence properties is investigated. The changes inthese glass properties are related to the glass structure modificationsinduced by the addition of P<sub>2</sub>O<sub>5</sub> and/or Al<sub>2</sub>O<sub>3</sub>, which were probed by FTIR, <sup>11</sup>BMAS NMR and X-ray photoelectron spectroscopies. Variations of thepolymerization degree of the silicate tetrahedra and modifications inthe <sup>[3]</sup>B/<sup>[4]</sup>B ratio are explained by a charge compensation mechanism due to the formation of AlO<sub>4</sub>, PO<sub>4</sub> groups and the formation of AlOP linkages in the glass network. From the absorption and luminescence properties of the Er<sup>3+</sup> ions at 980 nm and 1530 nm, declustering is suspected for the highest P<sub>2</sub>O<sub>5</sub> concentrations while for the highest Al<sub>2</sub>O<sub>3</sub> concentrations no declustering is observed.
