✦ Synopsis

A strong and systematic enhancement of the quasi-2D exciton photoluminescence in a variety of GaSb/AlSb multi-quantum well (MQW) structures, exposed to a low-energy hydrogen ion-gun treatment, is reported. Changes in the luminescence of the underlying GaAs substrate shows that hydrogen penetration through the entire MQW is warranted. The general behavior is indicative of an efficient passivation of nonradiative recombination centers either in the bulk of GaSb or at interfaces.

The change in the local structure and electronic configuration in CeFe2 and CeRu, after hydridation have been studied by EXAFS and XANES spectroscopies. Hydridation originate the amorphization of the Ce sublattice and the locakzation of the 4f electrons in Ce and 3d electrons in iron.
