Quantum Materials 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. Minimizing 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. "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."

Quantum Materials is also making significant advances with Cadmium-free
quantum dots, which are currently in evaluation stage by some of the
world's largest display manufacturers. Quantum Materials' products are
the foundation for technologically superior, energy efficient and
environmentally sound LCD UHD displays, the next generation of
solid-state lighting, solar photovoltaic power applications, advanced
battery and energy storage solutions, biotech imaging, and biomedical
theranostics.

Quantum dots are easily integrated into industry-standard thin-film
roll-to-roll inkjet and surface deposition technologies currently used
in existing LCD display production lines, as illustrated in an
