Er3+-doped amorphous tellurite thin films

Résumé

Radio‐frequency (RF) magnetron sputtering was used to deposit amorphous tellurite thin films from glassy targets from TeO2–ZnO–Na2O/BaO/Bi2O3 system doped with 2.5 mol% of Er2O3. The impact of the sputtering power on the optical, luminescence, and structural properties of the films is discussed. The deposition process leads to amorphous and transparent films which emit light in the visible and near‐infrared confirming the presence of Er3+ in the films’ network. Owing to their large refractive index and stability overtime, the Bi containing films are potential materials for integrated photonics and optical switches.
