Quantum dot deal aims to boost solid-state brightness
High brightness leads to efficient use of materials and increased performance in electronic displays and solid state (LED) lighting.
Quantum Materials plans to integrate the LANL thick-shell technology into the company’s quantum dot product line. The company’s automated process is capable of manufacturing industrial-scale quantities while maintaining tight uniformity and makes possible the reliable, economical production of thick-shell tetrapod quantum dots having the exact characteristics necessary for specific applications.
LANL scientists discovered that thick-shelling quantum dots reduces fluorescence intermittency by better separating absorption by the shell and emission by the core which suppresses blinking.
Commercial product lifetimes can be increased in QD-LCD backplane displays, solid state lighting films and projection lighting because the thick-shell technology has demonstrated the ability to extend the service life of quantum dots exposed to higher temperatures and/or high intensity light. Further, non-blinking quantum dots that can produce higher light output with less heat generation will spur new product development and optimized design.
LANL also achieved thick-shell ‘Giant’ QD near-infrared (NIR) emission for a major advance affecting medical imaging applications, optoelectronics, lasers, telecommunication and solar photovoltaics. For example, targeted cancer cells will be easier to identify and track, and varied absorption and emission ranges offer tailored performance in electronics and solar designs.
"We believe that the number of quantum dot performance improvements afforded by adding thick-shell technology to our Tetrapod Quantum Dots will set us significantly ahead of our competition. Our ability to manufacture uniform industrial-scale quantities of quantum dots engineered for optimal application-specific performance parameters will expedite acceptance of these new technologies by display and lighting manufacturers," explained Stephen B. Squires, Quantum Materials CEO and Founder.
David Doderer, QMC VP of R&D added: "Combining LANL thick-shelling abilities with QMC’s tetrapod quantum dots’ properties of high uniformity, and narrow emission (higher color purity) will be revolutionary in affecting quantum dot lifetime, quality of performance, enhancing of stability, and color rendering."
The technology was made available through LANL’s new Express Licensing Program. Dr. Jennifer Hollingsworth, of the Center for Integrated Technologies (CINT) at LANL is the Principal Investigator for Thick-Shell Quantum Dots.
