제목 Photopatternable cadmium-free quantum dots with ene-functionalization
초록 Photopatternable ligands improve the dispersability of nanoparticles into polymeric matrices and used to fabricate optoelectronic devices for display, sensing and quantum information processing applications[1-2]. Here we report the first instance of a cadmium-free photopatternable quantum dot. A ligand containing dithiolane group at one end and an ene-functionalization at the other end was synthesized for this purpose[3]. The myristic acid ligands on as synthesized red indium zinc phosphide-zinc sulfide (In(Zn)P/ZnS) quantum dots were easily replaced by the newly developed ligand by a simple sonication procedure. The functionalized quantum dots could be easily incorporated into a commercially available photoresist. The quantum dot doped photoresist was used to fabricate three-dimensional quantum dot doped hierarchical microstructures by two-photon lithography. Confocal imaging microscopy was used to verify the uniform incorporation of the nanoparticles in the hybrid microstructure.
