Abstract:
In this work, rutile-phase TiO2 nanoparticles (np-TiO2) are embedded within a Spin-On Glass oxide matrix (using a simple and economic Sol-Gel method) and the final TiO2/SiO2 mixture is directly deposited on stripes of aluminum so that the electronic, physical, chemical and photocatalytic characteristics of the final dielectric structure are obtained and correlated when irradiated with UV-Vis light sources. The I-V characteristics of this simple structure present a reduction in its total resistance when irradiated with UV light (compared to dark conditions), thus revealing a very simple photoresistor with relatively-low quantum efficiency.
