We present direct experimental evidence of photo-induced movement of photoluminescent quantum dots (QDs) dispersed in a photopolymerizable acrylate mixture. The resulting rearrangement of QDs into a spatially modulated pattern fixed in the polymer matrix is evidenced thanks to fluorescence microscopy.
