Nanoimprinted photonic component for light extraction applications

In this paper, the preparation of nanocomposites based on the incorporation of pre-synthesized (CdSe)ZnS core-shell luminescent nanocrystals (NCs) both in a PMMA (poly-methyl methacrylate) homo-polymer and into properly functionalized PMMA co-polymers is discussed. By using this novel luminescent nanocomposite materials, 2D photonic crystals are fabricated by Nanoimprint Lithography (NIL) and characterized, showing an effective enhancement in light extraction, likely to impact the fabrication of high-efficiency LED based on polymers by a cost efficient lithography technique.
