The effective medium model is applied to investigate the optical properties of hybrid nanocomposite layers Polyvinylcarbazole (PVK) and nanoparticles Zinc Selenide (ZnSe). Thin films PVK:ZnSe nanocomposites show a porous microstructure with pore diameters 500 nm. Numerical calculations led determination constants such as refractive index n, extinction coefficient k, dielectric permittivity ε, absorption α. Using common theoretical models, we have determined Cauchy parameters index, namely,...
The aim of this paper is to study the effect erbium oxide (Er 2 O 3 ) on porous silicon (PS) wafers used for photovoltaic application. An immersion PS in Er solution can be enhance light trapping and form an efficient surface by passivation process. was prepared stain-etching method doped species. In fact, topography investigated scanning electron microscope (SEM). addition, spectral behaviors reflectivity photoluminescence were discussed. dependence minority carrier lifetime evaluated means...
