Detecting mid-infrared (MIR) light is vital for applications ranging from sensing of gases in the atmosphere to biomedical typing oftissues, since molecules absorb at characteristic vibration bonds in the MIR. However sensitive detection of MIR light is problematicbecause unlike for visible light, detectors are bulky, costly and need to be cooled. Sensitive pixelated detectors for imaging areextremely expensive, precluding their use in many applications.We have invented and patented a new way to more efficiently detect MIR light, by upconverting it into the visible where efficient Sidetectors are ubiquitous. While upconversion is known, it is low efficiency in all materials, which has required it to be enhanced usingshort pulse lasers that are also expensive, bulky, and costly. Our devices use extreme confinement of light far below the opticalwavelength into few-nm gaps between coinage metals (such as Au or Ag). By thus confining both MIR and visible light in the samenano-gap, the upconversion efficiency is enhanced more than a billion-fold, enabling compact cheap detectors using diode laser orLED illumination. This leads to MIR detectors that are compact, uncooled, and much lower cost for users.This project will develop single-pixel and array detector demonstrators, identify and tabulate the technical specifications, build links topartners across the EU and UK, develop an IP plan, examine the capability for scale-up fabrication, and scope the range of marketsthat can be accessed

检测中红外（miR）光对于从大气中的气体传感到生物医学键入的应用至关重要，因为分子在miR中的特征振动键下吸收。但是，对mir光的敏感检测是有问题的，因为与可见光不同，检测器笨重，昂贵，需要冷却。用于成像的敏感像素化探测器非常昂贵，排除了它们在许多应用中的使用。我们通过将其将其倾倒到可见的，有效的侧室无处不在的情况下，发明并获得了一种新的方法来更有效地检测Mir Light。虽然已知上的转换，但所有材料的效率都低，这需要增强它，从而增强了脉搏激光器，这些激光器也昂贵，笨重且昂贵。我们的设备将光线的极端限制远低于光波长度，以在造币金属之间（例如AU或AG）之间的几个nM差距中。因此，通过将MIR和可见光限制在Samenano间隙中的光线中，上转换效率的提高了超过十亿倍，可以使用二极管激光器使用二极管廉价检测器。这会导致用户紧凑，未冷却且成本要低得多的miR探测器。该项目将开发单像素和阵列探测器演示器，识别和制表技术规格，构建欧盟和英国的构建链接，制定IP计划，检查一个IP计划，检查扩大规模的能力，并可以访问市场范围。
