摘要: Abstract Nanocomposite films composed of gold nanoparticles (AuNPs) embedded in a TiO 2 matrix have been prepared by direct liquid injection chemical vapor deposition process, using preformed and titanium isopropoxide as precursors. The spherical AuNPs about 4.1 nm diameter were synthesized (III) chloride trihydrate stabilized thiol ligands. depositions carried out performing at first oxide deposition, then nanoparticle one capping with oxide. morphology, structure; the state optical properties nanocomposite characterized scanning electron microscopy, Raman, X-ray photoelectron UV–Vis absorption spectroscopies, respectively. stability upon thermal annealing up to 800 °C was studied.
