Influence of controlled crystallization and SrF2 content on the structure and properties of Eu3+ doped phosphate glasses
Abstract
New phosphate glasses and glass-ceramics P2O5–Bi2O3–K2O–Nb2O5-SrF2 doped with Eu were synthesized and studied in this work. The influence of the SrF2 content (0–15 mol%) and the parameters of the heat treatment on their structural and optical properties were investigated. For the above purpose, the structural characterization by FTIR spectroscopy and XRD measurements was carried out, which showed a significant effect of SrF2 on the obtained crystal phases and the structure of the glass matrix. The results of combined DSC/DTA techniques enabled the determination of thermal properties and complemented the investigated crystallization characteristics of the glasses. Based on the measurements of the luminescence properties and the decay curves, it was confirmed that the Eu3+ ions were partially incorporated into the crystallites embedded in the glass matrix, which resulted in a significant enhancement of the luminescence. The conducted research confirms that the presented materials are a promising candidate for resistant phosphors in visible LEDs.
