Espectroscopia Ultravioleta-Visible ****

La espectroscopia Ultravioleta-Visible (UV-vis) se ha empleado como método de caracterización tanto de películas depositadas en substrato sólido como para el análisis de sustancias en disolución en el intervalo de longitudes de onda comprendida entre 190-820 nm.

**** _{Los fundamentos de la espectroscopia UV-Vis no serán desarrollados en la presente tesis dado su gran}

El equipo utilizado ha sido un espectrofotómetro Ultravioleta-Visible de diodos
