Kurzfassung
The goal of this thesis is the development of a new temperature sensitive paint for a temperature range between 0°C to 60°C with a lifetime < 100 µs. Therefore, Eu3+ and Sm3+ complexes are synthesised, and the chemical and physical properties are characterized. Aiming for a high temperature sensitive, high emission intensity and short lifetime TSP, the different approaches and results are mentioned. Within this work the following hypotheses are investigated: 1. Samarium β-diketone complexes are potential transient TSP luminophores with lifetimes shorter than 50 µs. 2. The implementation of electron donor and acceptor substituents within in β-diketone structure influences the emission intensity and temperature sensitivity. 3. Eu(II) phosphors are potential inorganic alternatives for transient TSP applications with proper chemical and physical properties. Achieving these goals involves the synthesis and characterization of the ligands and the complexes in cooperation with the FH Münster University of Applied Science at the department of chemical engineering in the laboratory for photonic materials of Prof. Schäferling. Furthermore, the physical properties like excitation, emission, temperature sensitivity and lifetime of the prepared TSP samples is evaluated at DLR Göttingen. For an impression of a practical application, the prepared samples are investigated in a wind tunnel environment.
