Leading UK-based nanomaterials innovator Quantum Science has announced its latest significant commercial success with the news that research and development specialists can now access two of its Quantum Dot (QD) products through the prestigious Merck platform.
Ready to ship from October
Following a rigorous quality control process lasting almost one year, the infrared QDs are now available on Merck’s Sigma-Aldrich website and will be ready to ship from early October.
The high-performance QDs are designed with absorption maxima of λ 1550 nm and λ 1350 nm respectively, meaning each is sensitive to a distinct wavelength of infrared light. This makes them suitable for use in cutting-edge photodiode device stacks that can then be used in sensors and imagers, unlocking game-changing new applications for self-driving cars, next-generation medical imaging, 3D mapping for smartphones, and more.
INFIQ® QD technology offers enhanced precision and greater flexibility for near-infrared (NIR) and short-wave infrared (SWIR) sensors and imagers compared to incumbent silicon-based alternatives due to the inherent limitations of silicon.
Current technology can only accomplish a comparable level of enhanced SWIR sensitivity using indium-gallium-arsenide (InGaAs) solutions, which are prohibitively expensive owing to their complex fabrication process. QD solutions offer greater throughput and can be produced at lower cost – by a magnitude of several thousand times – than InGaAs equivalents, making them viable for mass market commercialisation.
The news follows recent breakthroughs by Quantum Science in its development of lead-free QDs and QD inks, with grant funding expected to turbocharge its innovation in these areas.
