Quantum Materials Breaks Stokes Shift Barrier

'Strong Shift' quantum dots now available in commercial quantities

Quantum Materials Corp has announced it has broken the Stokes shift barrier and is able to produce 'Strong Shift' quantum dots to consistent characteristics in high volumes. The company announced the news on the opening of the second-annual Quantum Dots Forum hosted by Smithers Apex on March 18 at the San Francisco Grand Hyatt.

Named after Irish physicist George G. Stokes, Stokes shift is the difference between quantum dot's peak excitation and the peak emission wavelengths. Minimising overlap between total excitation and emission bands enhances the clarity and brightness of the fluorescing quantum dot by avoiding re-absorption of emitted light into nearby quantum dots - characteristics that display manufacturers and end-users find highly desirable.

Until now it has not been possible to produce Stokes shift in quantum dots of up to 20nm in quantities suitable for manufacturing applications, but Quantum Material's patent-protected continuous flow production process enables automated synthesis with uniformity necessary for achieving precise characteristics for high-volume production of highly-driven Strong Shift quantum dots.

"Our team is pushing the performance envelope for nanomaterials and widely expanding the range of viable applications," said Quantum Materials Corp CEO Stephen Squires. "

He continued: "Breaking the Stokes shift barrier allows manufacturers to benefit from more consistency in light output and less lost fluorescence due to overlap. The really extraordinary aspect is that in whatever area of quantum science our team advances, our patented reactor technology allows us to very quickly scale for volume production. If we were working with beaker batches like our competitors it would be both difficult and time consuming - and in some cases impossible - to achieve scaled production due to the challenge in maintaining uniformity of zero-overlap Stokes shift quantum dot synthesis in small batch quantities."



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.
