Scientific and Technical Objectives
The objective of this project is to develop a new, environmentally friendly and yet versatile materials technology platform for photonic and optoelectronic devices based on polymer composites of tailored Nanocarbons, targeted specifically to the eye-safe 2 m near-infrared region, with enormous potential e.g. in industrial processing, free-space communications & medical procedures, but well beyond what is currently widely accessible.
A specific novel objective is to prepare tailored nanoscale optoelectronic materials by noncovalently coupling dye aggregates to carbon nanotubes and graphene. This clean approach is a new pathway to derive transformative functionalities in nanoscale materials. In addition, this particular "bottom-up" approach enables us to correlate the atomic structure of the assembled nanostructures to their optical and optoelectronic properties, facilitating the elucidation of the fundamental mechanism of photosensitisation.
The general logic structure of the project is best shown graphically.
Selected target application
- Light trapping structures for improved photovoltaic devices.
- Near Infrared (NIR) photoemitting structures to demonstrate NIR OLEDs and possible NIR lasers.
- Nonlinear optical applications including broadband optical limiters and modelockers, and ultrafast all-optical switches.
