Composites Based on Polylactide Doped with Amorphous Europium(III) Complex as Perspective Thermosensitive Luminescent Materials

This work reports fabrication of polylactide (PLA) films doped with various additives an amorphous Eu(III) complex. We study the temperature behavior luminescence intensity and lifetime PLA-Eu(III) composites in range 298–353 K investigate mechanism quenching. The peak relative sensitivity reaches 20.1 %×K−1 exceeds respective characteristics all known lanthanide-containing thermosensors designed for physiological temperatures. produced can be potential novel materials luminescent thermosensors.
