Abstract

In this work, nanometer thickness dielectric layers deposited from colloid solutions using irradiation with Short Wavelength (SW) in the visible domain have been investigated by the Differential Evanescent Light Intensity (DELI) method. A high intensity UV filtered irradiation lamp was used for photodepositing nano-layers, directly on glass substrates serving as waveguides. The amorphous Selenium (a-Se) nanometric thin layers were deposited as circular zones of about ~ 1 cm² area. Polypropylene and Polyethylene compounds melted on glass waveguides were also analyzed by DELI.
