Preparation of nanostructures oxides films using electrochemical methods for sensor purposes

Abstract

The proposal of this research project is the development of nanostructured porous anodic alumina films (PAA) and its application for optical sensors. At the beginning we intend to investigate all experimental parameters related to the fabrication of PAA films in order to refine its optical properties. In a second stage, it is proposed a new methodology to investigate these optical properties, in particular the luminescence emission, which must be developed and refined in order to acquire a reasonable analytical signal. This will be achieved with the aid of in-situ optical measurements techniques and making use of multivariable analytical tools. The most important stage of this project will be the PAA film modification using self-assembly techniques, such as layer-by-layer technique, which will improve the quality of the films and its analytical properties (sensibility and selectivity). Aside from the large versatility of opto-electronics applications, some basic concepts related to the development and refinement of these optical sensors devices still remain incomplete and controversial. To master these aspects in the nanoscopic range represents a strategic positioning and a challenge for the research of new materials in our country. (AU)
