Combined X-ray photoelectron and Raman spectroscopies (XPS-Raman)

我们的目标是扩大我们在混合纳米光子结构的研究能力和努力，以增强光-物质相互作用和混合纳米材料的能量转换，要求一个组合的xps -拉曼系统提供功能纳米材料的化学和光学特性。该系统将集成在我们的表征实验室中，并结合互补技术，如紫外可见和荧光光谱，气相色谱，电化学工作站，红外光谱，显微镜和成像，动态光散射，阳光模拟器光源，3D纳米打印机等。这将代表一种独特的实验方法，以扩大我们在传感、催化、纳米光学和能量转换等方面应用的混合胶体和纳米材料的研究。通过确定纳米结构的化学成分及其在光激发下的响应，我们的目标是揭示纳米材料固有的化学和光学特性，并在将其集成到功能器件中时最大化其光-物质相互作用。我们纳米材料的光学性质和化学成分之间的相关性不仅是我们小组的突破，也是我们研究所所有小组和物理学院（LMU）的突破。该设备还将有助于我们小组开始的一个新的研究领域，即光激发下混合纳米催化剂的能量传递过程的研究。在这些纳米材料中，化学成分和光激发的控制不仅是非常理想的，而且是必要的，以便在现场了解这些纳米材料的功能。首选的xps -拉曼系统的特点是有独特的机会将两者结合起来：纳米结构的最终化学成分和光学表征以及光激发与化学鉴定。由于我们主要研究的是光活化材料，因此将拉曼光谱与XPS光谱相结合的可能性将有助于我们设计和合成用于能量转换的新型纳米材料，并研究光激发下表面成分的动态变化。此外，作为LMU和慕尼黑地区（TUM， MPI等）具有此类功能的第一个也是迄今为止唯一的设备；我们设想社区对访问这样的设施非常感兴趣，这使我们能够扩展我们的合作者网络并获得许多其他技术。

We aim to expand our capabilities and endeavors in the research of hybrid nanophotonic structures for enhanced light-matter interaction and hybrid nanomaterials for energy conversion by requesting a combined XPS-Raman system offering chemical and optical characterization of functional nanomaterials. The system will be integrated in our characterization laboratory and combined with complementary techniques such as UV-vis and fluorescence spectroscopies, gas chromatography, electrochemical working station, IR spectroscopy, microscopy and imaging, dynamic light scattering, sunlight-simulator light sources, 3D nanoscribe printer machine, among others. This will represent a unique experimental approach to expand our efforts in the research of hybrid colloids and nanomaterials for application in sensing, catalysis, nano-optics and energy conversion in general. By identifying the chemical composition of our nanostructures and their response under light excitation, we aim to unveil the intrinsic chemical and optical properties of nanomaterials and to maximize their light-matter interaction when integrating them into functional devices. The correlation between optical properties and chemical composition of our nanomaterials will be a breakthrough not only for our group but also for all the groups at our Institute and in general to the Faculty of Physics (LMU). The equipment will also aid in a new field of research starting in our group, the study of energy transfer processes in hybrid nanocatalysts under light excitation. In these nanomaterials the control of both chemical composition and optical excitation is not only highly desirable, but also necessary, in order to understand in-situ the functioning of these nanomaterials. The preferred XPS-Raman system is characterized by the unique opportunity to combine both: ultimate chemical composition and optical characterization of our nanostructures and light excitation with chemical identification. As we mostly work with light-activated materials, the possibility to combine Raman spectroscopy with XPS spectroscopy would certainly help us in the design and synthesis of new nanomaterials for energy conversion as well us to study the dynamic of the surface composition under light excitation. Furthermore, being the first and so far unique equipment with such capabilities in LMU and the Munich area (TUM, MPI, etc.); we envision a great interest of the community in accessing to a facility like this one, allowing us to expand our network of collaborators and gaining access to many other techniques.
