Eu3+ -doped polystyrene and polyvinylidene fluoride nanofibers made by electrospinning for photoluminescent fabric designing.

Eu3+ -doped polystyrene and polyvinylidene fluoride (PVDF/Eu3+ and PS/Eu3+ ) nanofibers were made using electrospinning. These fibers were characterized by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FT-IR), energy dispersive spectroscopy (EDX) and photoluminescence (PL). Spectral analysis of PVDF/Eu3+ and PS/Eu3+ nanofibers was based on their emission spectra. A bright red emission was noticed from Eu3+ that was assigned to the hypersensitive 5 D0  → 7 F2 transition. The enhanced intensity ratios of 5 D0  → 7 F2 to 5 D0  → 7 F1 transitions in the nanofibers indicated a more polarized chemical environment for the Eu3+ ions and greater hypersensitivity for the 5 D0  → 7 F2 transition, which showed the potential for application in various polymer optoelectronic devices. The Eu3+ -doped polymer (PVDF/Eu3+ and PS/Eu3+ ) nanofibers are suitable for the photoluminescent white light fabric design of smart textiles. This paper focuses on the potential application of smart fabrics to address challenges in human life.
