Zinc oxide nanorods have been synthesized by a hydrothermal method using a two different synthesis condition at low temperature. First sample have been grown at 122 C° temperature for 4 hours in the autoclave then at room temperature for two days and the second sample have been synthesized at 122C° for 4 hours in autoclave only. All products have been checked by using UV -Visible absorption and photoluminescence (PL), and the morphology have been studied by (FE-SEM), and AFM. In this work have been synthesized the hexanol nanorods (HZNR) at 122C° temperature for 4 hours in autoclave, while the Zinc oxide nanorod (ZNR) have been growth at 122C° for 4 hours in autoclave then two days at room temperature. UV-visible spectra show increased at excitonic absorption peaks in visible region with HZNR more than ZNR. All samples were observed that had high absorption in UV regain of spectra. Energy gup (Eg) degreased at HZNR (3) eV compared with ZNR (3.2) eV. In PL spectra, the band visible emission peaks were observed for all synthesized products (HZNR &ZNR) at 430 and 480 nm and high intense band centers at 688 for ZNR and 670 for HZNR However, the PL intensity peaks were reduced at (670 nm) for (HZNR) sample. the morphology of the sample was different when the temperature was changed. a hydrothermal method is uncomplicated, simple, cheap and environmentally, which made it favorable for huge -scale preparation for design and other application.
