Nanocomposite thin films consisting of a dielectric matrix, such as titanium oxide (TiO 2 ), with embedded gold (Au) nanoparticles were prepared and will be analysed and discussed in detail in the present work. The evolution of morphological and structural features was studied for a wide range of Au concentrations and for annealing treatments in air, for temperatures ranging from 200 to 800 ºC. Major findings revealed that for low Au atomic concentrations (at. %), there are only traces of clustering, and just for relatively high annealing temperatures, T ≥ 500 ºC. Furthermore, the number of Au nanoparticles is extremely low, even for the highest annealing temperature, T = 800 ºC.It is noteworthy that the TiO 2 matrix also crystallizes in the anatase phase for annealing temperatures above 300 ºC.
