摘要：

Core only of CdSe and core-shell quamtum dots (QDs) of CdS/ZnS, CdSe/ZnS and CdSe/ZnSe were functionalized with photosensitive monolayer to make them solution processable and photopatternable. Exchange of ligands was successfully followed using IR spectroscopic techniques. Core-shell type QDs were found to have better photoluminescence properties. Upon exposure to ultraviolet radiation these material were found to undergo polymerization forming interconnected arrays of QDs. These materials were found suitable for spin casting on organic and inorganic substrates. A highly efficient flourene-based two-photon sensitizer was mixed with QD dispersion of a urethane acrylate resin. Two-photon nanostereolithography using a mode-locked Ti:sapphire laser was applied on this resin mixture to fabricate three-dimensional (3D) microstructure. 3D microstructures fabricated were found with uniform dispersion of RGB QDs when observed through confocal microscope.
