发光光谱仪将用于无机和有机化学不同研究小组进行的结晶无机固体，配位化合物和螺烯衍生物作为有机光催化剂的研究。应用领域包括紫外-可见-红外区域的稳态和时间分辨光谱。此外，所要求的配置允许记录温度依赖的光谱，包括在低温下，量子效率的测定和通过多通道检测快速记录光谱。所要求的光谱仪将用于研究潜在的新型光催化剂以及稀土掺杂材料的性质，例如量子信息技术和光化学材料。此外，它允许观察与发光反应物的反应途径。在低温下的测量产生振动精细结构的更好分辨率或更窄的线宽;例如，在宽温度范围内的测量允许确定发光猝灭温度或在热释光测量框架内调查缺陷。例如，关于线宽的知识对于量子信息技术非常重要。温度依赖的光学性质和关于缺陷的知识在无机固态磷光体的开发中起着巨大的作用。特别是在红外区域的量子信息新材料的开发变得越来越重要，因为这将允许使用现有的玻璃纤维网络。

The luminescence spectrometer will be used for the investigation of crystalline inorganic solids, coordination compounds and helicene derivatives as organic photocatalysts carried out by different research groups in Inorganic and Organic Chemistry. The application areas cover both steady state and time-resolved spectroscopy in the UVVis to IR region. Furthermore, the requested configuration allows to record temperature-dependent spectra including at low temperatures, the determination of quantum efficiencies and the fast recording of spectra via multi-channel detection.The requested spectrometer will be used to investigate the properties of potential novel photocatalysts as well as rare-earth doped materials, for example for quantum information technologies, and materials for photovoltaics. Furthermore, it allows to observe reaction pathways with luminescent reactants. Measurements at low temperatures yield a better resolution of vibrational fine structures or much narrower line widths; measurements in a wide temperature range for example allow for the determination of luminescence quenching temperatures or the investigation of defects within the frame of thermoluminescence measurements. Knowlee regarding line widths is, for example, of great importance for quantum information technology. Temperature-dependent optical properties and knowledge regarding defects play an enormous role in the development of inorganic solid state phosphors. Especially the development of new materials for quantum information in the IR-region is becoming more and more important, because this would allow to use the existent glass fiber networks.
