This article describes the synthesis of silicon nanocrystals (Si‐NCs) and their functionalization with three different surface groups. We also report the effects of various surface groups on the optical properties of Si‐NCs with similar particle size distribution. The Si‐NCs were characterized using various methods such as XRD, FT‐IR, transmission electron microscopy, and fluorescence spectroscopy. Butylamine (blue), trioctylphosphine oxide (yellow), and dodecyl (red) functionalized Si‐NCs dispersed in toluene under UV‐illumination.
