Aluminum oxide thin films attract research interest due to their properties. Aluminum acetate was used as an Al source with acetic acid, oxalic acid, and nitric acid as additives. The transmittance and the thickness of the films strongly depend on the additives, with the approximate bandgap energy changing from 5 ev to 5.4 ev. The aluminum oxide film deposited by dip-coating is presented great uniform surface morphology. The knowledge of the degradation kinetics of materials is essential for investigating the thermal stability of compounds. The acetic acid thin film proved to be the most efficient additive by demonstrating interesting optoelectronic properties. The thin films deposited by dip-coating were characterized by using X-ray grazing incidence diffraction, SEM, UV-Visible spectroscopy. Gamma aluminum oxide thin films prepared by acetic acid can be a good candidate for a wide range of optical applications.

各种添加剂对浸涂法制备氧化铝薄膜的影响、热行为、动力学和光学性能

氧化铝薄膜因其特性而引起研究兴趣。乙酸铝用作铝源，乙酸、草酸和硝酸作为添加剂。薄膜的透射率和厚度在很大程度上取决于添加剂，带隙能量从 5 ev 变为 5.4 ev。通过浸涂沉积的氧化铝膜呈现出非常均匀的表面形貌。材料降解动力学的知识对于研究化合物的热稳定性至关重要。通过展示有趣的光电特性，醋酸薄膜被证明是最有效的添加剂。通过使用 X 射线掠入射衍射、扫描电镜、紫外-可见光谱对浸涂沉积的薄膜进行表征。
