Abstract
This study investigates the role of samarium (Sm3+) ions in bioactive glass fibers based on 45S5, S53P4, and 13-93 compositions. The aim was to develop materials with combined optical sensing functionality and mechanical strength for degradable composite applications. Degradation of glasses was monitored using a proposed luminescence-based approach that tracks the intensity decay of Sm3+ emission at 600 nm under 405 nm excitation. Higher Sm2O3 content (2 mol.%) was found to reduce tensile strength and significantly slow down degradation, as indicated by longer luminescence decay times up to fivefold higher than for low-doped samples. Scanning electron microscopy with energy-dispersive spectroscopy (SEM/EDS) confirmed delayed hydroxyapatite formation at higher dopant levels. The results demonstrate that Sm3+ ions influence both structural integrity and surface reactivity, acting as network modifiers and optical makers. This dual functionality enables controlled degradation profiles alongside real-time monitoring. Such fibers are promising for use as reinforcing and sensing elements in bioresorbable polymer composites for bone regeneration and other tissue-engineering applications, where simultaneous mechanical performance and in situ degradation tracking are essential.
