Córdoba Física, Astronomía y Matemáticas thin films optical gap vitreous coatings Optical characterization The optical constants n(E) and k(E) of thin films lead-free vitreous coatings have been determined. The extinction coefficient k was measured in the VIS/UV range using absorption techniques and the real part of the complex index of refraction n was calculated by using the Kramers-Kronig analysis. The sample was prepared from recycled soda-lime glass and melting anhydrous boric oxide in varying proportions, and then deposited on (100) MgO substrates for optical measurements. These measurements shown an optical energy gap about 3.2 eV and high values of n and k in the ultraviolet region, as reported for vitreous materials doped with PbO 1999 artículo científico 1665-3521 https://www.redalyc.org/articulo.oa?id=94200923 en http://www.redalyc.org/revista.oa?id=942 Superficies y vacío application/pdf Sociedad Mexicana de Ciencia y Tecnología de Superficies y Materiales A.C.
