"Advancements in Non-Toxic Quantum Dots Revolutionize Consumer Infrared Imaging"
Researchers at ICFO, in collaboration with Qurv, have developed a new type of non-toxic silver telluride (Ag2Te) quantum dots for shortwave infrared (SWIR) photodetectors and image sensors, compatible with CMOS technology for consumer electronics. These quantum dots avoid the use of heavy metals like lead or mercury, complying with RoHS regulations, and exhibit high performance with a spectral range up to 1,600nm. The study, published in Nature Photonics, demonstrates the potential of these quantum dots in various applications, including automotive and service robotics, by enabling reliable operation in conditions like bright sunlight and fog. The team aims to further improve the performance and stability of these photodetectors for market applications.
