Abstract
In a recent paper [Opt. Laser. Technol. 112 (2019) 207–214] Manthrammel et al. studied the optical properties of nanostructured rose bengal thin films. The refractive index and extinction coefficient of samples were calculated based on the reflectance and phase angle between the incident and reflected signals for a particular wavenumber. It is showed in this comment that they have used a wrong relation to calculate the extinction coefficient and the calculated optical parameters based on the extinction coefficient such as dielectric constant, dielectric loss, optical conductivity and electrical conductivity are incorrect.
