Abstract
Supersonic jet-cooled Au/Si clusters have been produced using a laser ablation procedure. TOF mass spectra reveal a variety of different species consisting of Au and Si clusters as well as mixed AumSin aggregates with variable n and m numbers. The beam has been deposited to form a nanostructured film whose structure is constituted of gold nanoparticles embedded in an amorphous gold silicide matrix. The optical properties of the deposited layer are sensitive to temperatures as low as 150 degrees C with a sharp change at around 200 degrees C.| File | Dimensione | Formato | |
