  • Optical Band Gap Estimation of ZnO Nanorods

    Total transmittance (T) and reflectance (R) spectra of sample Z along with their diffuse components (T D and R D) appear in Figure 2. From this figure it is noticeable that the main sample-light interactions are diffuse in both cases associated with the roughness of the surface. Measured T and R were the properties of the stack BGSTiO 2-ZnO

  • How to Calculate Reflectance Sciencing

    Reflectance is a measure of the incident electromagnetic radiation that is reflected by a given interface. It is closely related to reflectivity but reflectance is more applicable to thin reflecting objects. Reflectance can vary for thin objects due to variations in the surface thickness and approaches the
