Infrared quantum dot (QD) technology expert Quantum Science has cemented its position as an industry leader by creating a lead-free QD that is sensitive to the 1550 nm wavelength.
Quantum Science’s latest breakthrough in QD synthesis means its INFIQ® technology offers unparalleled shortwave infrared (SWIR) sensitivity for lead-free materials.
This level of performance is unmatched anywhere else in the industry and accelerates SWIR sensing’s advance into the consumer market, unlocking exciting new applications in smartphones, wearables, driverless vehicles, and more.
The announcement follows Quantum Science’s achievement of 1,400 nm last year thanks to its innovative QD production process that overcomes the barriers that limited most lead-free QDs to just 1,200 nm.
Reaching 1,550 nm is significant due to the difficulty of growing long-wavelength, lead-free QDs with a fairly narrow size distribution and uniform shape. In particular, it becomes difficult to control QD growth without destroying the optical properties that make it suitable for device applications.
Dr Hao Pang, CEO and Founder of Quantum Science, said: “At Quantum Science, we are committed to leading innovation, and to supplying our partners and customers with state-of-the-art QD technology. The achievement of this 1,550 nm lead-free QD is a significant milestone for the SWIR industry, firmly positioning us as a leader in lead-free QD production.
“Making a 1200 nm lead-free QD has been very difficult and a great accomplishment, because it has great value for SWIR technology in the consumer market. However, as experts in infrared QD and QD solutions, the Quantum Science team is committed to pushing innovation beyond boundaries and we are always eager to offer the best solutions to our valued customers and partners. With a performance gain of 1,500 nm, our INFIQ is lead free® QD infrared technology is not only the most advanced solution for SWIR imaging and sensing on the market, it is also the industry’s most desirable choice.
“As the demand for SWIR sensitive semiconductor materials increases, unleaded QDs such as our INFIQ® lead-free infrared technology will be key to bringing SWIR to the consumer market. This technology provides real market disruption and pushes the boundaries of what lead-free nanotechnology can achieve.”
