Abstract
Anti-reflective (AR) properties of flowerlike alumina thin films with a small roughness of less than 100 nm have been studied on substrates such as soda-lime silica glass, non-alkali glass, and quartz glass. The highest AR effects were obtained on quartz glass substrate, which has the lowest refractive index of the three substrates. The reflectance of quartz glass substrates coated with flowerlike Al2O3 was less than 0.5% in the wavelength region from 300 to 720 nm.
