Carbon dots are an emerging class of carbon‐based nanostructures produced by low‐cost raw materials which exhibit a widely‐tunable photoluminescence and a high quantum yield. The potential of these nanomaterials as a substitute of semiconductor quantum dots in optoelectronics and biomedicine is very high, however they need a customized chemistry to be integrated in host‐guest systems or functionalized in core‐shell structures. This review is focused on recent advances of the sol‐gel chemistry applied to the C‐dots technology. The surface modification, the fine tailoring of the chemical composition and the embedding into a complex nanostructured material are the main targets of combining sol‐gel processing with C‐dots chemistry. In addition, the synergistic effect of the sol‐gel precursor combined with the C‐dots contribute to modify the intrinsic chemo‐physical properties of the dots, empowering the emission efficiency or enabling the tuning of the photoluminescence over a wide range of the visible spectrum.
