Abstract	This paper reports a facile means to gradually tailor refractive index from an ultra-low-n of 1.10–1.45 based on hollow silica nanospheres hybridized with acid-catalyzed silica. The influences of the hybridization on refractive index, thin-film uniformity, and roughness were systematically investigated. The single-layered antireflection (AR) coatings and the three-layered AR coatings were prepared using the hybridized thin films as building blocks. The former showed the near-perfect transmittance and reflectance, 99.16 and 0.42 %, respectively, at a single wavelength of 600 nm, while the average transmittance (T $_{ave}$) and reflectance (R $_{ave}$) from the near ultraviolet (UV) to the visible region (300–800 nm) were moderate; the latter demonstrated an excellent AR capability in broadband that T $_{ave}$ reaches 97.29 %, much higher than that of the single-layered AR coating, 95.86 %. More interestingly, the three-layered AR coating showed an average transmittance of 97.94 % in the near-UV wavelength range from 345 to 400 nm and it was 6.77 % higher than that of bare glass. Moreover, the three-layered AR coatings had the less degradation in transmission and surface morphology after the highly-accelerated temperature and humidity stress tests, and the wet abrasion scrub tests. The findings imply that both good optical performance and durability are likely to be achieved using the sol–gel derived multilayered AR coatings.
