TY - CHAP A1 - Wohlschläger, Maximilian A1 - Versen, Martin A1 - Laforsch, Christian T1 - Investigation of the Impact of CaCO3 Concentrations on the Fluorescence Lifetime of Polypropylene T2 - Conference on Lasers and Electro-Optics N2 - The impact of fillers on the fluorescence lifetime of polymers is still unknown. Investigating polypropylene containing different CaCO3 concentrations using FD-FLIM show an exponential increase in fluorescence lifetime proportional to the CaCO3 density in polypropylene.

The results show that the distinction and identification is possible in a graphical and calculative way.
