Quantum Materials Achieves 99.5 Percent Efficiency For Red QDs

Cadmium-free quantum dot improvement seen as pivotal step to true QD-LED displays

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.



AngelTech Live III: Join us on 12 April 2021!

AngelTech Live III will be broadcast on 12 April 2021, 10am BST, rebroadcast on 14 April (10am CTT) and 16 April (10am PST) and will feature online versions of the market-leading physical events: CS International and PIC International PLUS a brand new Silicon Semiconductor International Track!

Thanks to the great diversity of the semiconductor industry, we are always chasing new markets and developing a range of exciting technologies.

2021 is no different. Over the last few months interest in deep-UV LEDs has rocketed, due to its capability to disinfect and sanitise areas and combat Covid-19. We shall consider a roadmap for this device, along with technologies for boosting its output.

We shall also look at microLEDs, a display with many wonderful attributes, identifying processes for handling the mass transfer of tiny emitters that hold the key to commercialisation of this technology.

We shall also discuss electrification of transportation, underpinned by wide bandgap power electronics and supported by blue lasers that are ideal for processing copper.

Additional areas we will cover include the development of GaN ICs, to improve the reach of power electronics; the great strides that have been made with gallium oxide; and a look at new materials, such as cubic GaN and AlScN.

Having attracted 1500 delegates over the last 2 online summits, the 3rd event promises to be even bigger and better – with 3 interactive sessions over 1 day and will once again prove to be a key event across the semiconductor and photonic integrated circuits calendar.

So make sure you sign up today and discover the latest cutting edge developments across the compound semiconductor and integrated photonics value chain.
