Circular polarisation luminescence (CPL) emission spectroscopy is a powerful tool for probing the fundamental chiroptical features of optically emissive chiral molecular systems. However, uptake of CPL spectroscopy has been impeded by the limitations of conventional scanning monochromator (SM) CPL spectrometers, which are costly to acquire and maintain, and typically require tens of minutes to acquire a typical CPL spectrum. Here, we demonstrate a design of CPL spectrometer which uses rapid readout solid state (SS) spectrometer detectors and a dual channel optical layout to acquire CPL spectra in as little as 10 milliseconds. We validate and demonstrate equivalent CPL measurement by measuring CPL spectra of two reference europium(III) complexes. Further, we demonstrate time-gated CPL acquisition, enabling long-lived CPL luminescence to be distinguished from short-lived emission of other fluorescent species. We anticipate that SS-CPL spectrometers will enable flexible, rapid, and relatively low-cost CPL spectroscopy for diverse applications.

圆偏振发光（CPL）发射光谱是探测光发射手性分子系统的基本手性特征的有力工具。但是，常规扫描单色仪（SM）CPL光谱仪的局限性阻碍了CPL光谱仪的使用，传统扫描单色仪（SM）CPL光谱仪的获取和维护成本很高，并且通常需要数十分钟才能获得典型的CPL光谱。在这里，我们演示了一种CPL光谱仪的设计，它使用快速读出固态（SS）光谱仪检测器和双通道光学布局，可在短至10毫秒的时间内获取CPL光谱。我们通过测量两种参比euro（III）配合物的CPL光谱来验证和演示等效的CPL测量。此外，我们演示了按时间限制购买CPL，使长寿命的CPL发光与其他荧光物质的短寿命发射区分开。我们期望SS-CPL光谱仪能够为各种应用提供灵活，快速和相对低成本的CPL光谱。
