Breve História da Energia Solar

Ph.D. Thesis on Thermochemistry of Organometallic Compounds under the orientation of Professor Alberto R. Dias e J. A. Martinho Simões in Centro de Quí­mica Estrutural (1996).

Since 2002, my research interests lie in the fields of photochemistry and photophysics. This work encompasses a wide range of related topics, including the determination of fundamental photophysical and kinetic parameters pertaining multiequilibria of anthocyanins in ground and excited states. It is only by having a detailed understanding of all these factors that we can design systems in which we have control over the direction and outcome of photo-induced reactions, such as energy transfer or electron transfer. These processes are studied towards the development of commercially important materials, mainly  electroluminescent materials and materials suitable for photovoltaic apllications.
