One-step preparation of CdS nanocrystals supported on thiolated silica-gel matrix and evaluation of photocatalytic performance

► CdS nanocrystals were grown onto a thiolated silica. ► UV/vis and photoluminescence spectra depended on the matrix/Cd2+ proportion. ► Spectra reflected variations in crystallite size. ► Samples photocalyzed decolorization of dyes.
