An Epoxy Photoresist Modified by Luminescent Nanocrystals for the Fabrication of 3D High-Aspect-Ratio Microstructures

Jürgen Brugger, Vahid Fakhfouri

An epoxy-based negative-tone photoresist, which is known as a suitable material for high-aspect-ratio surface micromachining, is functionalized with red-light-emitting CdSe@ZnS nanocrystals (NCs). The proper selection of a common solvent for the NCs and th ...
