Silicon Nanocrystals: Cationic Silicon Nanocrystals with Colloidal Stability, pH‐Independent Positive Surface Charge and Size Tunable Photoluminescence in the Near‐Infrared to Red Spectral Range (Adv. Sci. 2/2016)

Abstract

Silicon nanocrystals (ncSi) displaying size‐dependent optoelectronic properties functionalized with cationic surface groups are synthesized through a versatile alkyl‐halide surface intermediate. In article number 1500263, together with anionic functionalized ncSi developed by the same group, G. A. Ozin and co‐workers envision numerous combinations to observe the interplay between large and small, cationic and anionic silicon nanocrystals.
