Quantum Materials Awarded Patent for Continuous Synthesis of High Quality Nanoparticles

Quantum Materials Corp today announced that the United States Patent and Trademark Office has granted Quantum Materials Corp Patent # 9577149 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,” Quantum Materials founder and CEO Stephen Squires stated. “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 (available at this LINK) covers the continuous-flow synthesis process for the preparation of high quality indium phosphide/zinc sulfide 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,” Mr. Squire concluded.
