Photoluminescence Properties of Eu(TTA)3Phen/PS-PMMA Polymer Blend Electrospun Nanofibers

Because of their 4f electrons, europium metal ions have incredibly crisp emission bands. As the overlaying 5s2 and 5p6 orbitals effectively protect 4f orbitals from the effects of external pressures. Complex forms of europium metal ions, such Eu(TTA)3Phen, have garnered a lot of concentration for of their high fluorescence emission efficiency, which is caused by the ligands' high absorption coefficient. The Europium complex Eu(TTA)3Phen doped PS-PMMA polymer mix, Eu (TTA)3Phen/PS, and Eu (TTA)3Phen/PMMA have been synthesized and reported here. The SEM picture, XRD and PL characterizations, and CIE chromaticity were used to characterize the synthesized nanofibers made using the electrospinning technology. The f–f electron transition of Eu3+ ions and the antenna effect of ligands provide this Europium β-diketon complex exceptional optical and luminous characteristics. Due to the extreme hypersensitive behaviour of the 5D0→7F2 transition, the photoluminescence emission spectrum of nanofibers exhibits very high intense red emission. Because Eu3+ ions separate in the polymer chain of molecules, there will be more contact between the polymer and Europium complexes, which explains why polymers, polystyrene (PS), and polymethyl methacrylate (PMMA) have good optical properties. This was made possible by the polymer nanofibers' even distribution of Eu3+. This is because the presence of polymer may cause the site symmetry of the Eu3+ ion to decrease, and the surrounding polymer media may distort it. This study demonstrates the possible use of electrospinning in a variety of polymer optoelectronic devices and emphasises its promising uses in the creation of protective textiles. Because electrospun nanofibers are strong, flexible, and have exceptional photoluminescence qualities, they are used in the newest technology for smart textiles to create smart fabrics for a variety of applications. These textiles provide as protection against a wide range of environmental threats.
