Quantum Materials Achieves 99.5 Percent Efficiency For Red QDs

US Quantum Dot manufacturer Quantum Materials Corp (QMC) says it gas achieved 99.5 percent quantum yield efficiency for the company’s pure red (630 nm emission peak) cadmium-free quantum dots.

At this point QMC’s pure red (630nm) cadmium-free quantum dots are believed to offer the highest photon conversion efficiency in the industry – even when compared with quantum dots made with cadmium – by other quantum dot manufacturers.

QMC’s pure red Cd-free quantum dots were manufactured via the company’s proprietary continuous-flow manufacturing process, assuring high uniformity through the high-volume production process.

“Our primary focus is on driving cadmium-free quantum dots as a phosphor replacement in OLED displays, in concordance with Apple’s recent announcement regarding their integration of quantum dot and OLED technologies into QD-LED for future iPhone displays.

“Our materials are the foundation for accelerating development of QD-LED displays and making them a reality for mobile devices. QD-LED display form factors are more desirable for mobile devices and quantum dots as a phosphor replacement will radically improve colour performance and energy efficiency over current OLED technology,” said Toshi Ando, QMC VP of marketing.

QMC says that its process is quickly scalable to industrial-volume production at a price point commercially viable for next-gen QD-LED display development efforts such as Apple’s.

“We have already made a great deal of progress working with our film partners to integrate our materials into optical film for LED display applications and it was a natural progression for us to leverage that experience into QD-LED photo resist film applications concluded Quantum Materials’ president and CEO Stephen Squires.
