• Nanohybrids composed of carbon dots and gold nanoparticles are of considerable interest for luminescence imaging, photocatalysis, luminescence sensing and nonlinear optics. We describe a method for controlled growth of Au nanoparticles on the carbon nanodots by photocatalytic reduction of Au(III) ions under blue light irradiation. The resulting Au–carbon dots nanohybrids exhibit enhanced nonlinear photoluminescence under near-infrared femtosecond laser excitation with intensity which sharply depends on the gold-to-carbon dots volume ratio. Bright broadband photoluminescence of nanohybrids makes them attractive for luminescent imaging.
