Direct observation of Eu atoms in AlN lattice and the first‐principles simulations

Rare‐earth metal (Eu)‐doped aluminum nitride has potential application as luminescence materials due to its unusual mechanical and physical properties, as well as high chemical stability. Here, we investigate the energetics, local structure and optical and electronic properties by means of a combination of experimental observations ( XDR , SEM , HR ‐ TEM and XANES ) and first‐principles simulations. Present study has revealed that Eu ions are...
