摘要：The invention relates to a method of modifying a layer having photocatalytic

and anti-fouling properties which is based on titanium dioxide (TiO2) and which can absorb

photons in the UV region and, in particular, in the UVA region, in order to render same

capable of absorbing photons in the visible spectrum, said TiO2-based layer being

applied to a substrate either directly or with the insertion of at least one functional sub-

layer. The invention is characterised in that the TiO2-based layer is subjected to a heat

treatment in an atmosphere comprising nitrogen or nitrogen and at least one reducing

gas for a sufficient period of time in order to obtain the desired visible photon

absorption property, said substrate and, if necessary, said sub-layer(s) having been

selected for their ability to withstand the heat treatment.
