Fluorescent silicon nanocrystals for bioimaging
… to a wide variety of targeting molecules. Silicon (Si) nanocrystal quantum dots in particular exhibit bright, size-dependent emission with visible to near infrared wavelengths and are biocompatible, making them potentially interesting for in vitro and in vivo bioimaging. Here, Si …

Optoelectronic properties of size-selected silicon nanocrystals
Thin films of silicon nanocrystals (Si-nc) were produced by laser pyrolysis of silan and accumulated on various substrates. Layer growth, optical properties, charge transport, photoluminescence (PL) and electroluminescence (EL) were investigated on these porous layers. A stick-ball model for layer …

Electrical and optical characterization of colloidal silicon nanocrystals
Colloidal silicon nanocrystals (SiNCs), due to their high photoluminescence efficiency and tunable bandgap, can be used to fabricate highly efficient hybrid nanocrystal-organic light-emitting-devices (NC-OLEDs) that emit in red or near infrared spectrum. Despite reports of outstanding device …

Silicon nanocrystals: from bio-imager to erbium sensitizer
… been centred on the light emitting properties of silicon nanocrystals and the possible applications of this particular material platform to various topics ranging from bio-imaging to erbium ion sensitization. Silicon nanocrystals as bio-imaging agent have been investigated by employing colloidal …

Theoretical study of nanocrystals and other functional nanostructures of silicon and alternative group - 14 elements
… present work is a theoretical ab initio study of silicon (mainly) and silicon-based or “silicon-like” Nanocrystals and nanostructures, such as core/shell quantum dots and ultra-thin nanowires of Si, Ge, and Sn. The main focus is on the quantum confinement of Si quantum dots and the description of …
