Color tuning systems of polymer doped with rare earth complexes

Abstract

Rare earth complexes were synthesized and doped into polymers resulting in luminescent films. The obtained systems were characterized with elemental analysis, IR, TGA/DTG and XRD techniques. Photoluminescence properties were investigated and processes of energy transfer and sensitization were studied. Monochromatic emissions of obtained polymeric systems enabled their potential applications in multicolor displays because of the primary colors emitted by TR3+: red (Sm3+ and Eu3+), blue (Gd3+) and green (Tb3+). The polymer matrix performs an essential role in the luminescent sensitization processes for systems containing Sm3+, Eu3+, Gd3+ and Tb3+, therefore the overall systems act as Light Conversion Molecular Devices (LCMDs).
