Current breakthroughs from Quantum Science’s lead-free (LF) focus staff have remodeled the steadiness of its INFIQ® LF-QD inks each at wavelengths of 1,100 nm and 1,400 nm.
Intensive testing has proven that INFIQ® LF-QD inks can stay secure for as much as a yr, each when it comes to their optical traits and machine efficiency. No shifts in optical absorption peaks, peak properties, or machine effectivity had been noticed throughout this era.
This overcomes challenges that almost all LF-QD inks expertise in sustaining stability over lengthy intervals as a result of discount in ligand dimension in contrast with QD supplies, supporting analysis and improvement by extending the shelf lifetime of QD options.
The INFIQ® LF-QD inks have additionally been confirmed to work on silicon wafers, facilitating high-scale short-wave infrared (SWIR) picture sensor manufacturing as much less ink is required to coat bigger wafers.
LF-QD inks are instrumental to bringing SWIR functionality into markets the place conventional heavy-metal based mostly QDs are restricted, reminiscent of client electronics and medical units.
Dr Hao Pang, CEO and Founding father of Quantum Science, mentioned: “At Quantum Science, we’re pushing the boundaries of SWIR expertise and this newest achievement by our world-leading staff in LF-QD formulation is a testomony to our imaginative and prescient of creating SWIR imaging and sensing accessible to all. Boosting the steadiness of LF-QD inks at 1,400 nm and 1,100 m to virtually a yr is a landmark second for the business, demonstrating the potential of this expertise and our drive to maintain constructing on efficiency.
“New functions for LF-QD inks are nonetheless rising as analysis and improvement professionals uncover use circumstances for them in client electronics, medical units, and way more. The power to retailer LF-QD inks for longer intervals will help analysis into new functions, bringing this world-changing expertise into merchandise we use day by day.”
