CFQD® quantum dots are Nanoco’s core technology, consisting of fluorescent semiconductor nanoparticles typically between 10 to 100 atoms in diameter, which is about 1/1000th the width of a human hair. When one of these particles is excited by an external light source, it absorbs the energy and re-emits the light in a different colour depending on the size of the particle. Therefore, by tuning the size of these particles, one is able to control the colour of light emitted to any colour in the spectrum.
Quantum dots can also be tuned for use in a variety of different media with adjustment of the surface ligands, opening them up to several different form factors (including our CFQD Fine Color FilmTM product ) and applications.
Nanoco Group PLC (LON:NANO) leads the world in the research, development and large-scale manufacture of heavy metal-free nanomaterials for use in displays, lighting, vertical farming, solar energy and bio-imaging.
