Paper Abstract

SiO2 films doped with the organic dye DO3, exhibiting high electron delocalization have been prepared by the sol- gel method and deposited on soda-lime glass substrates. On these films an electric field of 5-7 kV/cm has been successively applied in order to induce orientation of the DO3 molecules and freeze them in the condition by heating and reticulation of the inorganic matrix. The thermal stability of the films and the variation of the molecules' orientation as a function of time have been studied. The films have been characterized by means of differential thermal analysis, thermogravimetry, mass spectrometry, ellipsometry and atomic force microscopy.
