Quantum Materials Secures Los Alamos Thick-Shell Quantum Dot Technology to Increase Brightness and Stability in Consumer Electronics
SAN MARCOS, Texas, Feb. 19, 2014 /PRNewswire/ -- Quantum Materials Corporation (OTCQB:QTMM) and Los Alamos National Laboratory’s (LANL) today announce Quantum Materials optioning Thick-Shell ‘Giant” Quantum Dot patented technology with the potential of 10 to 100-fold improvement in solid-state brightness over conventional nanocrystal quantum dots (QD). High brightness leads to efficient use of materials and increased performance in electronic displays and solid state (LED) lighting.
“Blinking” is a tendency of quantum dots to flash off momentarily often noted as a challenge for certain quantum dot applications. LANL scientists also discovered that thick-shelling quantum dots dramatically reduces fluorescence intermittency by better separating absorption by the shell and emission by the core, significantly suppressing blinking (see diagram).
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.
Quantum Materials plans to integrate the LANL thick-shell technology into its 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.
Stephen B. Squires, Quantum Materials CEO and Founder said, “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.”
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.
