This work investigates the reflectance properties of nanostructured glass surfaces modeled as random monolayers of air spheres embedded in a glass matrix. The study employs three analytical models: the Maxwell-Garnett Model (MGM), the 2D Dipole Model (2-DMM), and the Coherent Scattering Model (CSM). All models predicted a decrease in reflectance due to the nanostructuring of the glass surface. This decrease in reflectance is particularly significant, reaching up to almost 20% across the entire visible spectrum, for nanostructures with 15% surface coverage and crater radii of 50nm. Each model’s suitability, advantages, and limitations are discussed in the context of varying particle sizes and surface coverages.
