Here, polyvinyl alcohol (PVA)-based microfibers comprising nanoparticles were fabricated via a simple stretching method as a highly luminescent and flexible material. The structural and optical features of the prepared microfibers were investigated using X-ray Diffraction (XRD), field emission scanning emission microscopy (FESEM) image and ion beam induced luminescence (IBIL) techniques. Utilizing XRD analysis, related tetragonal phase of Bi₂WO₆and polymer based PVA peaks were found in the prepared microfibers. Prepared Bi₂WO₆microfiber exhibited strong blue-green emission upon excitation of 2.2 MeV proton beam and under a UV lamp at room temperature. Furthermore, microfiber diameter was obtained in the range of 8-33 m. This highly luminescent microfiber is believed to be a good candidate for optical sensor and wearable optoelectronic applications. https://ppam.semnan.ac.ir/article_7634_77bb14f6132ea06dea456584b7d5581e.pdf
