Abstract:
In the fields of science and engineering, photoluminescent fibers have been employed for a variety of purposes, including optical storage, biological labeling, noninvasive imaging, solid-state lasers, light-emitting diodes, spectrum modifiers, and temperature sensors. 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 Bi۲WO۶ and polymer based PVA peaks were found in the prepared microfibers. Prepared Bi۲WO۶ microfiber exhibited strong blue-green emission upon excitation of ۲.۲ MeV proton beam and under a UV lamp at room temperature. Furthermore, microfiber diameter was obtained in the range of ۸-۳۳ m. This highly luminescent microfiber is believed to be a good candidate for optical sensor and wearable optoelectronic applications.
