Use of quantum dots in electronic components continues to grow as manufacturers develop new sensor and display technologies.
UK-based Nanoco has signed a five-year development and supply deal to provide US semiconductor manufacturer ST Microelectronics with cadmium-free quantum dots for use in infrared sensors.
Quantum dots are nanometre-sized semiconductor particles that emit light in various colours, creating a high resolution for use in display screens, sensors and solar panels. Quantum dots used to be largely cadmium-based, but regulations to restrict the use of cadmium, which is toxic, has prompted developers to move towards substituting indium phosphide.
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
