Effect of Catalysts on Preparation of Sol-Gel Derived Si02 Antireflective Coating

Article Preview

Abstract:

Based on TEOS system and sol-gel process, together with catalysts, the microstructure of SiO2 particles in the sol is exactly controlled. The films are characterized by ellipsometer and SEM respectively. The experimental results show that adjusting catalytic agent can effectively effect the structure of SiO2 thin film.
