Description: 
Although in the last decades rare earths (REs)-containing materials have been proposed as active media in Si compatible light sources, the reached optical efficiency is still limited by the low REs excitation cross section. In this work, the introduction of Bi as an Er sensitizer in a Si-compatible yttrium oxide thin film has been proposed in order to overcome this limit. The stabilization of optically active Bi 3+ ions in place of Y 3+ in the two reticular sites, S 6 and C 2, of Y 2 O 3 was demonstrated. Photoluminescence (PL) and …
