Photogeneration of Fluorescent Silver Nanoclusters in Polymer Microgels

Photoactivated template-based synthesis of fluorescent Ag nanoclusters in the interior of microgel particles has been demonstrated. Photoluminescence intensity and emission wavelength varies with the time of photoactivated synthesis. Optical properties of the photogenerated Ag nanoclusters strongly depend on the acidity of the medium. The resulting hybrid microgels show stable photoluminescence and strong response to external stimuli.
