Fabrication and structural properties of flower-like TiO2 nanorod array films grown on glass substrate without FTO layer
For the first time, flower-like titanium dioxide (TiO2) nanorod array (TFNA) films were grown on sputtered TiO2 seed layer-coated glass substrate without fluorine-doped tin oxide (FTO) layer during 1–5 h immersions. The optimum immersion time was 4 h, which produced a dense TFNA structure with thick...

| Summary: | For the first time, flower-like titanium dioxide (TiO2) nanorod array (TFNA) films were grown on sputtered TiO2 seed layer-coated glass substrate without fluorine-doped tin oxide (FTO) layer during 1–5 h immersions. The optimum immersion time was 4 h, which produced a dense TFNA structure with thickness of 19 µm. X-ray diffraction results revealed that the TFNA were of a tetragonal rutile phase. A humidity sensor, fabricated using the prepared sample, showed excellent humidity sensor performance, with sensitivity reaching up to 196. The results indicate that the prepared TFNA films are promising material for humidity sensing applications. © 2020 Elsevier B.V. |
