Indium-zinc oxide (IZO) nanofibers are synthesized on Si-SiO2 substrates by the electrospinning method. The nanofibers’ dimensions, morphology, crystalline structure, and composition are studied by scanning electron microscopy, atomic force microscopy, energy dispersive X-ray analysis, and X-ray diffraction. The results of studying the electrical properties of nanofibers, as well as their sensitivity to UV radiation depending on the In to Zn concentration ratio, are presented. It is shown that the highest sensitivity to UV is observed at the indium content of about 50 atomic %. The photocurrent increment in this case, with respect to the dark current, is more than 4 orders of magnitude. The response and recovery times are 60 and 500 s, respectively. The results obtained suggest that IZO nanofibers can find application as UV sensors with improved characteristics.
