Colourful displays by tuning of surface plasmon resonances

August 13,2015

The team around Prof. Debashis Chanda from the University of Central Florida (US) has developed a reflective display exhibiting continous colour tuning over a large range of the visible colour spectrum. As recently reported in the journal "nature communications", they used a Photonic Professional system to pattern an array of nanowells covered with aluminium. This array acts as a wavelength selective reflector and in combination with liquid crystals, the device enables the electrical tuning of the surface plasmon resonance to enable a flexible colour display.
