Covers the continuous-flow synthesis process for making InP/ZnS  core/shell semiconducting nanocrystals 

Quantum Materials has been awarded a patent by the United States Patent and Trademark Office for the continuous synthesis of high quantum yield InP/ZnS nanocrystals.

"This is an important milestone in consolidating and protecting our intellectual property for large scale volume synthesis of non-cadmium quantum dots," said Quantum Materials founder and CEO Stephen Squires.

"Continuous synthesis micro-reaction technology is the solution for synthesis of high-quality nanoparticles due to the many advantages our patented process provides, including precise temperature control, mixing efficiencies, fast reaction speed and parallel operation for scalable volume production."

United States Patent # 9577149 covers the continuous-flow synthesis process for the preparation of high quality InP/ZnS  core/shell semiconducting nanocrystals - in particular quantum dots (QD) -  conducted in a micro-reaction system comprising at least one mixing chamber connected to one reaction chamber.

"We have begun continuous-flow volume production of high-efficiency blue quantum dots that we believe will play an important role in the future of quantum dot light-emitting diodes (QD-LEDs). Prior to this point, blue quantum dots exhibited unfavorable energy levels in comparison to red and green quantum dots with respect to device efficiency," Squire concluded.

Analyst group Gartner has recently named Quantum Materials as one of five 2017 Cool Vendors in 3D Printing for the company's solution to the problem of counterfeit 3D printed parts "“ embedding light-emitting quantum dots in 3D printing plastic resins for product identification that is nearly impossible to counterfeit. 

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.
