Abstract
In a recent paper [Physica B 552 (2019) 62–70] Assiri et al. studied the optical properties of the spin-coated nanostructured methyl violet-10B (MV-10B) 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 shown 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 absorption coefficient, band gap energy, dielectric constant, dielectric loss, optical conductivity and electrical conductivity are incorrect.
