Nanoscale semiconductor particles, especially in the form of quantum dots (QDs), are increasingly being applied across sectors such as autonomous vehicles, food inspection, medical devices, and artificial intelligence. These industries are actively seeking greater access to infrared data, and lead sulfide-based QDs, such as those in Quantum Science’s INFIQ technology, play a crucial role. By adjusting the wavelengths of these QDs across the near and shortwave infrared spectrum, sensors fitted with this technology can capture extensive, otherwise invisible data. QDs offer a proven, cost-effective approach, delivering the advanced material sensing capabilities essential to these industries.
Quantum Science recently announced a breakthrough in lead-free QD technology, capable of detecting wavelengths up to 1,550 nm. This non-toxic, high-performance solution is set to unlock new applications in short-wave infrared (SWIR) technology for consumer electronics, providing a safer alternative without compromising on functionality.
Cheaper alternatives to traditional indium-gallium-arsenide (InGaAs) sensors have already impacted the SWIR market, a space worth billions. Machine vision companies are seeing real benefits from affordable, high-resolution imaging technology with low pixel pitch.
Quantum Science’s CEO and founder, Dr Hao Pang, has highlighted SWIR’s potential to revolutionise imaging and sensing by expanding the data range accessible to devices. As more vision industry companies invest in SWIR-enabled cameras, applications continue to grow—from enhancing artificial intelligence with higher quality, invisible data to powering industrial cameras that can sort plastic waste, benefiting environmental sustainability. According to Dr Pang, SWIR is set to drive the next major step forward in these sectors.
The expansion of QD technology into SWIR applications holds significant promise for industries reliant on data-driven precision and advanced imaging, paving the way for enhanced performance in various technological and environmental applications.
