Theory of optical properties of nanowire metamaterial with gain

In this work, we demonstrate a non-monotonic dependence of nanowire metamaterial optical coefficients on the surrounding media’s gain. The effect is based on the field redistribution between the lossy nanowires and the amplifying host matrix and it significantly depends on the metamaterial lattice constant.

Stabilization of organic solar cells

In this work additives such as UV absorbers are implemented into organic solar cells to improve their overall lifetime (FTP-project Stabil-O). In a new project starting 2017 (CompliantPV), this is extended to improve also mechanical stability in flexible devices.

Coupling of plasmonic surfaces with organic nanostructures

In this work we show that the optical response of organic materials can be controlled by forming organic-plasmonic hybrid systems. The interaction between organic nanoaggregates and engineered optical near fields may lead to strongly enhanced optical response. Furthermore, the strong plasmonic-exciton interaction might be interesting for plasmonic applications, where organic nanofibers could be exploited as active components, responsible for plasmon generation or modulation.

Chiral assemblies from achiral organic building blocks

Deposition of MOP4 on mica leads to two types of nanofibers, “L” and “R”. Their images in a mirror “M” cannot brought in coincidence with themselves, similar to a left and a right hand. This “chirality” is induced by the substrate.

Improved sensor materials for harsh environments

In collaboration with Danfoss Industrial Automation, NanoSYD researchers have developed new sensor materials that can operate at elevated temperatures. This has led both to an improved basic understanding of the material systems and opportunities for product improvement.
