Quantum Materials breaks Stokes-shift barrier in quantum dots, leading to brighter displays

March 18, 2015
"Strong-shift" QDs have consistent characteristics in high volumes.

Quantum Materials Corp. (San Marcos, TX; OTCQB:QTMM) says it has broken the Stokes-shift barrier that limits the performance of quantum dots (QDs) for displays, and is able to produce "strong-shift" QDs to consistent characteristics in high volumes. The company made the announcement at the opening of the second annual Quantum Dots Forum hosted by Smithers Apex (March 18; San Francisco, CA).

Named after Irish physicist George Stokes, the Stokes shift is the difference between a QD's peak excitation and peak emission wavelengths. Minimizing overlap between excitation and emission bands enhances the clarity and brightness of the fluorescing QD by avoiding re-absorption of emitted light into nearby QDs. Quantum Materials says that until now it has not been possible to produce a Stokes shift in QDs of up to 20 nm in quantities suitable for manufacturing applications, but Quantum Material's continuous-flow production process (which the company has patented) enables automated synthesis with the uniformity necessary for achieving precise characteristics for high-volume production of highly-driven strong-shift QDs.

Cadmium-free QDs
Quantum Materials says it is also making significant advances in cadmium-free QDs, which are currently in the evaluation stage at some large display manufacturers. In addition to ultrahigh-definition liquid-crystal displays, such QDs are also useful in solid-state lighting, solar photovoltaic power applications, advanced battery and energy storage, 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 informative video detailing cadmium-free quantum dot uses and benefits, which is also available for download at http://bit.ly/1KhSS9i for use with attribution.
