The obtained results show that the structure and the size of Au clusters, together with the matrix crystallinity, changed as a result of the annealing As a result of these structural variations the film optical properties were modified too. The optical changes, and the correspondent Surface Plasmon Resonance effect were confirmed by reflectivity and CIELab colour measurements. XRD analysis confirmed the presence of gold in all the samples, and the crystallization of the TiO2 matrix for the samples annealed at temperatures above 4000C. With further increase of the annealing temperature, there is a change from the TiO2 anatase phase into rutile-type structure. Simultaneously, the Au atoms are organized in crystalline nanoparticles (revealing an fcc-type structure, with the (111) preferential growth orientation).
