Theoretical and Experimental Investigation of Al3+ Ion-Suppressed Phase-Separation Structures in Rare-Earth-Doped High-Phosphorus Silica Glasses

Through advanced topological engineering, the cross-linking in phase-separated network chains was finely tuned to synthesize high-phosphorus silica-based glasses co-doped with erbium and ytterbium, resulting in exceptional uniformity and improved spectral performance.
