Abstract

We reported photochromism and largely enhanced visible two-photon luminescence (TPL) of Ag-TiO2 granular composite films by using ps/fs laser at the wavelength of 800 nm. Three types of photochromism spectra were observed when the Ag atom fraction are less than, comparable to and larger than the percolation threshold. The strong surface-plasmon-resonance enhanced visible TPL emissions near Ag2O transition band from the photoactivated Ag-TiO2 samples were also observed. Furthermore, we found that the TPL intensity saturatedly increased while the absorbance at 800 nm exponentially decreased with the same rate as the increasing of photoactivation time, which means that both photochromism and TPL of Ag-TiO2 composite films are originated from the photo-oxidation of Ag to Ag+. These observations exhibit the multifunctional features of Ag nanoparticle materials.
