Photoluminescent Nanocomposites from two-dimensional Silicon Nanosheets

Silicon nanosheets (SiNSs) are two-dimensional semiconducting materials with a layer thickness in the nano regime and sheet sizes up to the micro scale. They exhibit outstanding electronic properties which in combination with their structural characteristics make them a promising new material for applications such as lithium-ion-batteries and nanoelectronics. As synthesized from CaSi2 SiNSs (also referred to as layered polysilanes) are hydride terminated an prone to oxidation under ambient conditions. For further applications they need to be stabilized with organic mieties. We here present a concept that allows the simultaneous functionalization of the SiNSs while a polymeric matrix is formed. The nanocomposite shows improved stabilities of the SiNSs against external influences and combines the optoelectronic features of the SiNSs with the processing properties of the polymer matrix.     «
