Analysis methods and response values
Measuring of fluorescence spectra (stationary) and measuring of fluorescence intensity
depending on time ("time-drive")
Aim
Aim
- Determining position and intensity of fluorescence bands and their changes due to chemical and/or physical processes
- Investigations concerning the light-induced decomposition of substances
- Examination concerning the fluorescence behavior of additives (dyes) depending on the polymer matrix
- Measuring of fluorescence quenching in dependence on parameters like dye concentration, matrix material, production etc.
