Recent advances of our group on the study of preparation and non-linear optical response of high-performance mesoporous-based nanocomposite films are summarized. Special attentions are focused on new methodology design for the highly efficient and homogeneous incorporation of the metal or semiconductor nanoparticles in the pore channels of mesoporous thin films. These new methodologies include like-dissolves-like, ion-exchange, electroless deposition, electric deposition, deposition-precipitation and surface-modification protocols with mesoporous silica or titania matrix. Afterwards, the non-linear optical responses of the resultant nanocomposite films and the thermally post-treated ones in the presence or absence of magnetic field are analyzed. Finally, some perspectives for the further development of mesoporous nanocomposites films are also discussed.
