This preliminary study reports the effective fabrication of a potential radiation dosimetry material made of 4.91 M n-ZnO, n-5 wt% WO3 and PVA solution coated on glass substrates utilizing the electrospinning technique with nanofiber collecting times of 2, 3 and 4 h. FESEM and EDX are used to analyze the samples’ morphology and elemental composition. The nanofibers form a mat-like structure with a diameter range of 1.48–1.9 µm. Then, W shows at.% and wt% decline as the nanofibers collecting times increase from 2 to 4 h, whereas the nanofibers sample collected within 3 h has the highest at.% and wt% of Zn. All samples display crystalline wurtzite structure for ZnO and hexagonal phase for WO3, according to the XRD study of crystallinity. Meanwhile, all samples have Eg ranging between 3.17 and 3.24 eV. The electrospun n-ZnO/n-WO3/PVA nanofibers (4.91 M n-ZnO and 5 wt% n-WO3) thin film coated glass, prepared at 3 h nanofibers collecting times, can be proposed as a potential material for dosimetry applications because it exhibits the best X-ray attenuation when compared to other samples, despite the small amount of n-ZnO used in this preliminary study.
