Nanoscale materials such as quantum dots, carbon nanotubes, nanoparticles and nanostructures exhibit strong spatial confinement upon photo-excitation and tuneable emission, which makes them extremely useful in photonic applications.
Emission at desired wavelengths has been widely demonstrated in the past, however research is currently focused on improving the quantum yield as well as the photo-stability and chemical stability for example in core/shell geometries. New materials are investigated in the zeroth dimension in dots, the second in sheets such as graphene, or the third in nanostructures, whereas applications from optoelectronic devices to medical diagnostics and quantum computing.
The fluorescence emission, quantum yield and lifetime of nanoscale materials can be characterised with a range of Edinburgh Instruments’ products.
