A one-step method to synthesize nanorice fluorine-doped tin oxide (nr-FTO) was successfully applied to a bare FTO substrate via a hydrothermal process. This technique successfully creates uniform films of nr-FTO with spherical morphology. According to FESEM analysis, FTO nanorice has an average grain size of 54.8 nm in length and 21.0 nm in diameter. This technique provides a simple fabrication procedure to create nanorice FTO thin films without requiring an extra seed layer. The data from XRD analysis and the d-spacing values obtained from TEM imaging are in good agreement, further demonstrating the crystalline character of the synthesized nr-FTO. The chemical analysis provided by the EDS results further indicates the excellent purity of the nanorice FTO thin film. The one-step hydrothermal synthesis method described here offers a quick and effective way to create high-quality nr-FTO thin films for various uses.
