ZnO is an important multifunctional material for many different applications in biosensors such as light-emitting diodes (LED), UV sensors and widely used in fabrication of solar cell devices. The performance of such devices strongly depends on the nanostructures of the thin film used. This research was conducted to analyze the effect of variations in growth temperature of 70℃, 80℃, 90℃ and 100℃ with Niobium doped 3% weight to physical properties of the resulted ZnO which has been grown by seed mediated hydrothermal method. The optical absorption, morphology, element composition and crystalinity of the samples were analyzed using UV-Vis characterization, Scanning Electron Microscope (SEM), Energy Dispersive X-Ray (EDX) and X-Ray Diffraction (XRD). The UV-Vis spectrum shows that a strong absorption occurs in the wavelength range of 350-380 nm with optimum absorption and smallest band gap of 3,07 eV was obtained at growth temperature of 90℃. The SEM images show that geometrical shape of Nb-doped ZnO nanostructure is nanorod with hexagonal cross-sectional and nanoflower faced shape. This hexagonal cross-sectioal is tapered at growth temperature of 100℃. The EDX spectrum shows that the elements contained ZnO sample consisting of C, O, Si, Ca and Zn while the elements contained in Nb-doped ZnO sample consisting of C, O, Si, Ca, Zn and Nb. XRD patterns observed show five diffraction peaks with crystal orientation of (100), (002), (101), (102) and (110). The strongest line was found in the crystal plane of (101) at growth temperature of 90℃. The results of this study indicate that the optimal nanorod film is Nb-doped ZnO with growth temperature of 90℃.
