Stimulated Opticaltransitions in Er-Doped Silicon Nanostructures
Published online by Cambridge University Press: 11 February 2011
Abstract
Photoluminescence (PL) of Er3+ ions in nanocrystalline (amorphous) silicon matrix has been investigated under a high level of optical excitation. A superlinear increase of the PL intensity, a shortening of the PL decay time, and strong angular dependence were found at the excitation intensity above 200 kW/cm2. These effects are observed only in samples with presence of silicon nanocrystalls and explained by stimulated optical transitions.
