ABSTRACT
We present an overview of light-emitting devices based on Si-
nc, including both a general theoretical frame and the whole
experimental progress attained in the field. Several materials and
two basic device structures will be presented to elucidate the
emission properties. A dedicated section illustrates the strategies
applied to extend the emission spectra either to the green-blue
portion of the visible spectrum or to the infrared one, with special
attention to the telecommunication band at 1.55 μm.
