Due to the quantum confinement, silicon nanoclusters (Si-ncs) embedded in a dielectric matrix are of prime interest for new optoelectronics and microelectronics applications. In this context, SiO x /SiO 2 multilayers have been prepared by magnetron sputtering and subsequently annealed to induce phase separation and Si clusters growth. The aim of this paper is to study phase separation...
Erbium ions have been used as active ions in optical amplifiers because 1.54 mum luminescence due to 4I13/2 rarr4I15/2 4f transition is sharp and intrinsic almost independently of temperature and host matrix, and also corresponds with standard optical telecommunication window. In order to overcome the small absorption cross-section of Er ions, the Er sensitizer such as Yb3+ ions has been introduced...
