Multicolor polymer nanocomposites: In situ synthesis and fabrication of 3D microstructures

The multiphoton polymerization of CdS-polymer nanocomposites is used to fabricate 3D luminescent structures such as the multicolor microbull shown in the figure. The CdS nanoparticles are synthesized in situ within the polymer matrices with their size controlled by the amount of added crosslinker.
