We report gamma radiation-induced effects on the electrical properties of low-cost and easily scalable synthesis of TiO₂ nanorods of diameter ~ 20–80 nm on fluorine-doped tin oxide (FTO)-coated glass substrates using the hydrothermal method. X-ray diffraction studies show a rutile crystallographic phase which is highly textured along the (002) crystallographic plane. These nanorods are uniformly grown on FTO/glass substrate and nearly aligned normally to the surface plane. Raman studies confirm the observed rutile phase, showing all probable Raman vibrational modes. The bandgap of the synthesized TiO₂ nanorods is around ~ 3.14 eV. ⁶⁰Co gamma radiation source is used for irradiating gamma doses from 375 mGy to 3000 mGy. We observed that the leakage current increases linearly with increasing gamma radiation dose. These findings suggest that TiO₂ nanorods on FTO/glass substrates can be used for efficient gamma radiation dosimetry.

我们报告了使用水热法在氟掺杂氧化锡（FTO）涂层的玻璃基板上以低成本，易于扩展的直径〜20–80 nm的TiO ₂纳米棒的低成本，易于扩展的合成对伽马辐射诱导的电性能的影响。X射线衍射研究表明，金红石晶相沿（002）晶面高度织构化。这些纳米棒均匀地生长在FTO /玻璃基板上，并且几乎垂直于表面平面。拉曼研究证实了观察到的金红石相，显示了所有可能的拉曼振动模式。合成的TiO ₂纳米棒的带隙约为3.14 eV。⁶⁰伽玛射线辐射源用于辐照从375 mGy到3000 mGy的伽玛剂量。我们观察到，泄漏电流随着伽马辐射剂量的增加而线性增加。这些发现表明，FTO /玻璃基板上的TiO ₂纳米棒可用于有效的伽马辐射剂量测定。
