ZnO nanorods were synthesized in the presence of cationic surfactant N-cetyl-N,N,N-trimethyl ammonium bromide (CTAB) at 180 °C using hydrothermal method with zink nitrate tetrahidrate and ammonia as starting materials. The synthesis sample was calcinations at three different temperatures of 300, 500, and 700 °C for 2 h, respectively. Structural and optical properties are studied by using X-ray diffractometer (XRD), Scanning Electron Microscopy (SEM), Transmission Electron Microscopy (TEM), and Ultrasonic Violet Visible (UV Vis). XRD results indicate the formation of pure phase hexagonal wurzite, crystalline size maximum in 700 °C calcination temperature. SEM results indicate the particle size decrease with increase in calcination temperature to 700 °C. The TEM micrograph shows the presence of ZnO nanorods with diameter around 77 nm. Optical properties by UV Vis analyzed show that band gap values increase with the increase in calcination temperature, high transmittance values are observed by increasing the calcination temperature, and low reflectance observed by increases the calcination temperature. |
