Eu -doped polystyrene and polyvinylidene fluoride (PVDF/Eu and PS/Eu ) 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/Eu and PS/Eu nanofibers was based on their emission spectra. A bright red emission was noticed from Eu that was assigned to the hypersensitive D → F transition. The enhanced intensity ratios of D → F to D → F transitions in the nanofibers indicated a more polarized chemical environment for the Eu ions and greater hypersensitivity for the D → F transition, which showed the potential for application in various polymer optoelectronic devices. The Eu -doped polymer (PVDF/Eu and PS/Eu ) 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.
采用静电纺丝法制备了掺铕聚苯乙烯和聚偏氟乙烯（PVDF/Eu和PS/Eu）纳米纤维。通过扫描电子显微镜（SEM）、傅里叶变换红外光谱（FT-IR）、能量色散光谱（EDX）和光致发光（PL）对这些纤维进行了表征。PVDF/Eu和PS/Eu纳米纤维的光谱分析基于它们的发射光谱。观察到铕发出的亮红色发射，这归因于超灵敏的(^{5}D_{0}\to^{7}F_{2})跃迁。纳米纤维中(^{5}D_{0}\to^{7}F_{2})与(^{5}D_{0}\to^{7}F_{1})跃迁的强度比增强，表明铕离子的化学环境更具极化性，且(^{5}D_{0}\to^{7}F_{2})跃迁具有更高的超灵敏性，这显示了其在各种聚合物光电器件中的应用潜力。掺铕聚合物（PVDF/Eu和PS/Eu）纳米纤维适用于智能纺织品的光致发光白色织物设计。本文重点关注智能织物在应对人类生活挑战方面的潜在应用。
