Accurate measurement of optical constants for silver (Ag) is necessary for reliable theoretical predictions; however, measuring the optical properties of a layer while avoiding exposure to air is challenging. A novel method is used to measure the optical constants of silver in air without the problem of surface tarnishing and without the need for an ultra-highvacuum atmosphere. Since the optical constants vary with different grain sizes, the relationship between different grain size and the corresponding relaxation times is established.
