Because of their 4f electrons, europium metal ions have incredibly crisp emission bands. As the overlaying 5s2 and 5p6 orbitals effectively protect from effects external pressures. Complex forms ions, such Eu(TTA)3Phen, garnered a lot concentration for high fluorescence efficiency, which is caused by ligands' absorption coefficient. The Europium complex Eu(TTA)3Phen doped PS-PMMA polymer mix, Eu (TTA)3Phen/PS, (TTA)3Phen/PMMA been synthesized reported here. SEM picture, XRD PL...
Photoactive rare-earth (RE) complex electrospun nanofibers possess improved photoluminescence properties, thermal stability and mechanical flexibility with large surface area to volume pore size within nano range. In this paper, we report the fabrication of europium Eu(TTA)3phen using electrospinning technique. Europium (TTA=thenoyltrifluoroacetone, phen=1,10-phenanthroline) was synthesized by solution technique then used for preparation different polymers such as PMMA, PVdF PS study...
Eu3+ -doped polystyrene and polyvinylidene fluoride (PVDF/Eu3+ PS/Eu3+ ) nanofibers were made using electrospinning. These fibers characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), energy dispersive (EDX) photoluminescence (PL). Spectral analysis of PVDF/Eu3+ was based on their emission spectra. A bright red noticed from that assigned to the hypersensitive 5 D0 → 7 F2 transition. The enhanced intensity ratios F1 transitions in indicated a...
Europium complex Eu(TTA)3Phen (TTA=2-thenoyltrifluoroacetone, phen=1,10-phenanthroline) was synthesized by solution technique and then used for the preparation of electrospun nanofibers Eu(TTA)3phen/Polymers using polymers such as polymethylmethacrylate (PMMA) polyvinyldiflouride (PVDF) its combination as, PMMA-PVDF carrier. During electrospinning process fed to tip syringe pump at a flow rate 0.3 ml/hr. A positive voltage 20kV applied polymer solution, fibers were typically obtained...
The photoluminnescent trivalent rare earth europium ion (Eu3+) is well incorporated with polymers like Poly (vinylidene fluoride) PVDF and Poly(ethylene oxide) PEO to fabricate the PVDF/Eu3+ PEO/Eu3+ nanofibers by electrospinning technique. fabricated were characterized scanning electron microscopy energy dispersive x-ray spectroscopy (SEM-EDX), Fourier transform infrared (FTIR) diffraction (XRD).

It is very interesting to compare the influence of (Eu3+) &Eu(TTA)3phen doped polymers on PL characteristics electrospun polymer nanofibers. Because Eu3+, especially europium, are popular and known for their good luminescence. Here we present synthesis Eu3+ Eu (TTA)3phen polystyrene fibers as well a comparative study photoluminescence properties. Europium metal ions exhibit extremely sharp emission bands, Eu(TTA)3Phen has attracted much attention due its high efficiency. The synthesized...

Also, Localized defect...
In this paper, a Polyvinylidene fluoride (PVdF), Polymethylmethacrylate (PMMA), and Polystyrene (PS) blend nanofiber electrolyte membrane was prepared by using the electrospinning method. which ratio of PMMA PS is different. As produced electrospun nanofibers, polymer membranes were characterized scanning electron microscopy for morphology, FTIR miscibility, XRD, DSC TGA crystallinity thermal properties. The blended nanofibrous PVdF/PMMA/PS showed higher uptake, porosity, ionic conductivity...
Abstract The europium ion (Eu 3+ ) is well acknowledged and more popular for its strong luminescence when it compared with other RE ions. Here we report the comparative study of electrospun polymer nanofibers by using complex Eu(TTA)3phen electrospinning technique. Electrospun fibers Europium chloride were prepared PVDF to photoluminescence properties. Photoluminescence spectra these show very high intense red emission because hypersensitive behaviour 5 D 0 → 7 F 2 transition. These are much...
