In contrast to UV photomultiplier tubes that are widely used in physical chemistry, mid-infrared detectors are notorious for poor sensitivity and slow time response. This helps explain why, despite the importance of infrared spectroscopy in molecular science, mid-infrared fluorescence is not more widely used. In recent years, several new technologies have been developed that open new experimental possibilities for research in the mid-infrared. In this Account, we present one of the more promising technologies, superconducting nanowire single photon detectors (SNSPDs) by sharing our experience with its use in a typical experiment carried out by physical chemists (laser-induced fluorescence) and comparing the SNSPD to a detector commonly used by physical chemists (InSb at LN Temperature).

使用超导纳米线单光子探测器的纳秒级时间分辨率的中红外激光诱导荧光：分子科学新技术

与在物理化学中广泛使用的UV光电倍增管相反，中红外检测器因灵敏度低和响应时间慢而臭名昭著。这有助于解释为什么尽管红外光谱在分子科学中很重要，但中红外荧光却没有得到更广泛的应用。近年来，已经开发了几种新技术，这些新技术为中红外研究提供了新的实验可能性。在此帐户中，我们通过分享我们在物理化学家进行的典型实验（激光诱导的荧光）中使用它的经验并将SNSPD与检测器进行比较，介绍了一种更有前途的技术，即超导纳米线单光子检测器（SNSPD）。通常由物理化学家使用（InSb在LN温度下）。
