Optical properties of annealed nanostructured Zinc Oxide thin film exposed at different temperatures

This study presents result of the optical properties of Zinc Oxide (ZnO) thin film using glass substrate. All the substrate was clean used Acetone, methanol and hydrofluoric acid (HF). Sol-gel method used to prepared Nanostructured ZnO thin film. The precursors used Zinc Acetate, Ethanolamine as a stabilizer and 2-Methoxyethanol as solvents. 10 layers was deposited onto glass substrate by used spin-coating technique and annealed at from 200°C, 300°C, 400°C, 500°C and 600°C temperatures. Then, the substrate were exposed at room and high environment temperature with measure by following day namely day 1, day 3, day 7, day 15 and day 21. UV-Vis-NIR spectrophotometer is used to measure the optical properties.
