Quantum Science, an innovator in short-wave infrared (SWIR) quantum dot technology, has proudly announced it has been granted the UK's first patent for infrared lead-free quantum dots. This critical milestone consolidates the firm’s status as a leader in crafting the most robust IP portfolio in this field.
The new patent solidifies Quantum Science’s acclaimed stature, building on its stronghold in SWIR imaging markets. Known for their INFIQ® QDs, Quantum Science offers superior performance without the need for lead-based compounds, paving the way for broader commercial explorations from consumer gadgets to advanced industrial sensors.
Quantum Science’s intellectual property now boasts 11 patent families with 77 patents filed around the globe. This latest achievement underscores the company’s commitment to safeguarding innovations across the entire quantum dot value chain—spanning synthesis, surface modification, inks, ligand exchange, and device integration.
Dr Hao Pang, CEO and Founder of Quantum Science, said: “This is a significant breakthrough for both Quantum Science and the UK technology sector. By securing the UK’s first infrared lead-free quantum dot patent, we are demonstrating our ability to deliver technology that is world-class in performance while aligning with regulations around lead-based materials.”
The company’s pioneering work introduces a lead-free substitute to traditional lead sulphide-based quantum dots. This innovation promises a new wave of applications that maintain high performance while adhering to regulatory standards.
Quantum dots play a pivotal role across diverse sectors, from next-generation displays to biomedical imaging. Historically, optimal quantum dots have contained lead, complicating their market adoption due to environmental and regulatory challenges. Now, lead-free variants offer a promising solution, enabling broader adoption without sacrificing performance or sustainability.
Quantum Science’s trailblazing work continues to hone one of the most expansive QD patent portfolios worldwide, reinforcing its position as an industry leader. This patent exemplifies years of dedicated research and reflects the remarkable capabilities of the team and collaborators. It ensures their partners enjoy innovative technology and the confidence to thrive in competitive markets.
