The antireflective film refers to an optical thin film with the characteristics of reducing surface reflectivity and increasing transmittance. With the development of application fields such as solar energy, optical observation, and new optical systems, the demand for thin films with wide-angle antireflection properties is becoming increasingly urgent and has become a research hotspot in the optical field at home and abroad. This article introduces the latest progress in the preparation methods and properties of non-uniform gradient refractive index antireflective films by inclined deposition, dry etching, and wet etching, and analyzes and evaluates them. The challenges and feasible research directions faced in the preparation of non-uniform gradient refractive index antireflective films were discussed.
