Abstract :
Here for the synthesis of ZnO (Zinc Oxide) nanorods we have used hydrothermal process. Seed layers were deposited on FTO (Fluorine doped tin oxide) glass substrates using electro deposition method with zinc nitrate dehydrate. ZnO nanorods were synthesized on annealed seeded layer by hydrothermal method using hexamethylenetetramine as a precipitant and zinc nitrate dehydrate as source at different temperatures 50°C, 65°C, 75°C, and 85°C. The crystal surfaces were investigated by Scanning Electron Microscopy (SEM). SEM produces image by using electrons rather than light photons. A beam of electrons is sent by electron gun which follows the vertical path and after travelling through the magnetic lens it hits the sample. After the beam hits the sample, electrons and X-rays are ejected and collected by detector to give final image. It is found that the dimension of ZnO nanorods changed with different temperature. SEM images show that the average diameters of ZnO nanorods are about 10-15 nm by changing growth temperature. The smallest diameter of ZnO nanorods is observed while the growth temperature is equal to 50 ℃. ZnO nanorods have applications in Quantum Dot Sensitized Solar Cells (QDSSC).
