We implanted silica-titania sol-gel films with 3 • 10 15 at./cm 2 , 180 keV Er + and 6 • 10 16 at./cm 2 , 140 keV Ag + ions. The energies were chosen so that the profiles of Ag and Er overlap. RBS and ERDA were used to study the behaviour of Ag, Er and H during the heat treatments used to densify th
