Eu 2+ ‐Activated Osumilite‐Type Glass‐Ceramics for High‐Power White Lighting: Low‐Barrier Crystallization Driven by Topological Homology
High‐power white light‐emitting diodes (w‐LEDs) urgently require luminescent materials with excellent thermal stability and high color rendering, while conventional phosphors suffer severe luminescence quenching under high‐power excitation. Although aluminosilicate glass‐ceramics (GCs) are promising all‐inorganic e...
