Abstract: Polymeric optical fibers (POF) are processed at low temperatures allowing functionalizing the raw material prior to fiber fabrication. With this in mind POF or microstructure POF doped fibers can be prepared. In this work an extruded solid Poly(methyl methacrylate) (PMMA) fiber containing the complex diaqua(tristhenoyltrifluoroacetonate) europium(III) [Eu(tta)3(H2O)3] was prepared and characterized as a temperature sensor. The emission lifetime of the 5D0 state of the europium(III) ion was measured in the temperature range from 10°C to 60°C. The results show a linear and negative dependence between the emission lifetime and the fiber temperature with a proportional coefficient of (-2.27 ± 0.01) microseconds/°C. This represents a reduction of about 30% of the emission lifetime when changing 50°C the fiber temperature.
