Sintesis Dan Karakterisasi Nanorod Zno Didoping Logam Alkali Natrium (Na) Dengan Metode Seed Mediated Hydrothermal

---

Natrium doped ZnO nanorods were successfully grown on FTO substrates using the seed mediated hydrothermal method. The growth of the ZnO nanorods was carried out with variations in growth time of 5, 6, 7, 8, 9, 10, and 11 hours, using a concentration of 2% NaOH relative to the total solution volume. This research was conducted to investigate the physical properties of natrium doped ZnO nanorods under the influence of different growth times. The synthesized samples were characterized using UV-Vis spectroscopy, XRD, FESEM, and EDX. The UV-Vis spectra showed strong absorption in the wavelength range 300-350 nm for all samples. The strongest absorption of ZnO:Na occurred at a growth time of 8 hours, with a bandgap energy of 3,27 eV, which was lower than the bandgap energy of pure ZnO 3,37 eV. The XRD pattern of the samples displayed five diffraction peaks at 2θ angles of 31,74°; 34,43°; 36,25°; 47,57°; and 56,68° with the highest peak observed at 2θ = 36,25°. This highest diffraction peak occurs on the (101) plane, indicating that there is no significant change in the position and shape of the diffraction peak. FESEM images revealed that the geometry of the natrium doped ZnO nanomaterials is in the form of nanorods. The growth time exceeds 8 hours, the tips of the nanorods begin to split. The EDX spectra of the samples showed the presence of C, O, Zn, Na, and Sn elements, which are the basic components of the FTO substrate. This confirmed that the Na element was successfully incorporated into the ZnO nanorods.
