Continuing and extending the work done in project A1 in the first funding period of FOR 2824, we investigate adamantane-like clusters of the [(RT)4E6] type (R = organic substituent; T = Si, Ge, Sn; E = S, Se, Te), which under certain circumstances exhibit extreme nonlinear optical properties in the form of a spectrally broad (white-light) emission. In cooperation with the PIs of the other projects within FOR 2824, these compounds are investigated experimentally and theoretically with respect to their nonlinear optical properties and with respect to their microscopic and macroscopic structures; here, the substances also serve as benchmark compounds for new experimental and theoretical methods to study amorphous materials in general. Among the major long-term goals of FOR 2824 are understanding the physical mechanism behind the new form of white light generation and the use of the materials in engineered devices. Based on the results obtained in the first funding period, we are therefore targeting in project A1 those substances that are particularly suitable for the formation of homogeneous, robust samples with the desired white-light emission properties as a result of their combination of R/T/E (or R/R', T/T', E/E'). We will develop synthetic routes to new compounds where R, T, and E can be uniform or diverse. We also propose – also in cooperation with project A2 – promising extensions of the compound library toward extended cluster cores, multifunctional substituents, and polymeric materials. In the case of crystalline materials, we will determine their structures. However, in terms of white-light generation, amorphous materials are the focus of the project. Therefore, the control of amorphousness is another important goal of the project A1 in the second funding period. We want to influence this specifically through glass formation, by exposure to external pressure, and by incorporation into scaffolds. The most promising compounds, as determined by our own pre-screening using a simple laser setup and simple DFT calculations, will be passed on to the theorists and physicists in FOR 2824, who will then perform more detailed studies on them in close cooperation with us and ultimately use the compounds for the fabrication of test devices.

在2824年的第一个融资期内，我们继续研究A1项目中所做的工作，我们研究了[（RT）4E6]类型的类似Adamantane的类别（R =有机替代品； t = Si，ge，sn; e = S，Se，Se，te），在某些情况下，在某些情况下，在某些情况下，在某些情况下，在某些情况下，excression emsive of Emistion emistion emistion emistion emsision em em em em em em em em emsive em emsive。与2824年内其他项目的PI合作，这些化合物在实验和理论上就其非线性光学性质进行了研究，并在其显微镜和宏观结构方面进行了研究。在这里，这些物质还可以用作研究非晶材料的新实验和理论方法的基准化合物。 2824年的主要长期目标之一是了解新光发射新光的形式背后的物理机制以及在工程设备中使用材料的使用。因此，根据第一个融资期间获得的结果，我们针对项目A1的靶向这些物质，这些物质特别适合形成具有所需的白光发射特性的同质，可靠的样品，这是由于它们的R/T/E（或R/R/R'，r/r'，t/t/t/t'，t/t'，t'，e/e'）。我们将开发到r，t和E可以是统一或潜水员的新化合物的合成路线。我们还建议 - 还与项目A2合作 - 有希望的化合物库扩展到扩展的群集岩心，多功能亚电位和聚合物材料。对于结晶材料，我们将确定它们的结构。但是，就白光生成而言，无定形材料是该项目的重点。因此，对非晶态的控制是第二个资金期间项目A1的另一个重要目标。我们希望通过玻璃形成，暴露于外部压力以及在脚手架中的就业来具体影响这一点。最有希望的化合物由我们自己的预筛查使用简单的激光设置和简单的DFT计算确定，将传递给2824年的理论家和物理学家，然后他们将与我们密切合作，并最终使用该化合物来制造测试设备。
