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.
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. U
ntil 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 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.
