Scientists from the Institute of Photonics Science (ICFO) have developed a brand-new image processing chip. With the help of new nano-graphene and quantum dot mixing technology, for the first time, digital cameras can successfully capture both infrared and ultraviolet and visible light components. Image, ICFO's researchers deployed metal, PbS glue quality point (CQD) semiconductor materials on monolayer graphene, and use this hybrid system to place on CMOS wafers, connect to image processing chip package units and read Take the circuit.
In this way, the team succeeded in producing a high-resolution image sensor capable of sensing a wide range of spectral wavelengths at the same time, from ultraviolet rays at a wavelength of 300 nanometers to infrared rays at a wavelength of 2000 nanometers, and completely covering the visible light range. According to researcher co-author Gerasimos Konstantatos, “We have successfully extended QD technology to the near-infrared spectrum (1100-1900 nm), which allows our passive night vision technology to detect and display the atmosphere of a clear night sky at the same time.†The possibility of a high-sensitivity, low-cost far-infrared image sensor at room temperature is demonstrated, and it has a huge market prospect.
