Nov 14, 2012 · First Published:08 November 2012. Small silicon, big opportunities:A colloidallystable silicon nanocrystal (ncSi) polydispersion sizeseparated into monodisperse fractions exhibits photoluminescence blueshifting with decreasing particle size under photoexcitation. The ability to prepare ncSi monodispersions opens the door to access and study tunable sizedependent properties that promise to have a huge impact
An Investigation into Near-UV Hydrosilylation of The impact of reaction with alkenes and alkynes was studied using in situ photoluminescence (PL) spectroscopy, allowing measurement of both changes in intensity and PL maxima during the reaction. Understanding this behavior is important for the utilization of these materials in a number of applications where hydrosilylation is a leading method

To celebrate his 77th birthday, ASN reached out to the extraordinary Nanochemist at the University of Toronto, "the father of Nanochemistry", Geoffery Ozin, to discuss his colorful career, current projects, and plans for the future. The interview is summarized with the title "small materials with a big impact".
Visible Colloidal Nanocrystal Silicon Light-Emitting Diode We herein demonstrate visible electroluminescence from colloidal silicon in the form of a hybrid silicon quantum dotorganic light emitting diode. The silicon quantum dot emission arises from quantum confinement, and thus nanocrystal size tunable visible electroluminescence from our devices is highlighted. An external quantum efficiency of 0.7% was obtained at a drive voltage where device
