AbstractMultilayer broadband antireflective (AR) coatings consisting of porous layers usually suffers poor functional durability. Based on a quarter-half-quarter multilayer structure, AR coatings with dense SiO(2)film as the top layer are designed, and refractive index for each layer is optimized. After heat-treated at only 150 degrees C, refractive index of Nb(2)O(5)film reaches to 2.072 (at 550 nm), which can meet design requirements of the middle layer. TiO2-SiO(2)composites with controllable refractive indices are selected to be used as the bottom layer. The obtained triple-layer AR coating presents excellent performance, and the average transmittance at 400-800 nm attains 98.41%. Dense layers endow the multilayer structure good abrasion-resistance, and hexamethyldisilazane is further used to modify the surface of the AR coating, which can greatly improve the hydrophobicity of the coating. The proposed triple-layer broadband AR coating has potential value in practical applications of sol-gel deposition.
