Nanomultilayers of Al/Tb/Al/SiO 2 have been fabricated by e‐beam evaporation, alternatively depositing each layer. Optical characterization of the samples shows a narrow and strong green emission, indicating the optical activation of Tb 3+ ions. The electrical characterization revealed conduction limited by the electrode, although trapped‐assisted mechanisms can also contribute to transport. The electroluminescence analysis revealed also emission from Tb 3+ ions, yielded promising results to include this material in future optoelectronics applications as integrated emitting devices. This is reported by Sergi Hernández and co‐workers in article number 1700451 .
