“…28 Djurabekova and coworkers studied the amorphization and interface change of Ge and Si in amorphous silica under irradiation by MD simulation and revealed the least size of the crystal to correctly describe the interfacial structure. 18,29 However, the dynamic properties of interfaces, which are closely related to the stability of NGC materials during hightemperature consolidation, 7,12,30 have been rarely studied. These studies have not elucidated the structural correlations of interfacial dynamics and thus cannot effectively control interfacial diffusion.…”

By combining the spectroscopic quality of a crystalline phase with the outstanding thermal and chemical stability of the matrix glass, nanocrystal‐in‐glass composites (NGCs) exhibit excellent optical properties. However, strong interfacial diffusion occurs during high‐temperature encapsulation, leading to the erosion of the nanocrystals and detrimental effects on the final performance. The control of interfacial diffusion has so far relied on intuition and experience, with the underlying physical mechanisms remaining largely unknown. In this study, through atomistic simulations and experimental verification, we have developed atomic models of NGCs, revealing the dynamic characteristics of the interface and elucidating how the glass structure can regulate the interface diffusion. Finally, we demonstrate how a tunable interface can be achieved through compositional adjustments of the glass matrix.
