Abstract: Ag colloid self-assembled films (colloidal metal films) including monolayer (glass/(PVP_d-nanoAg)_1) and multilayer (glass/(PVP_d-nanoAg)_n) were fabricated by layer-by-layer self-assembly method, where PVP_d(poly(4-vinylpyridine)) was used to link metal nanoparticles by metal-ligand interactions. The obtained monolayer and multilayer films are optically stable at atnbient environment, as demonstrated by absorption spectrum measurements. The plasmon resonance of isolated Ag nanoparticles (individual plasmon resonance) and collective plasmon resonance (interparticle plasmon resonance) were observed simultaneously for both mono- and multilayer films. And the intralayer collective resonance in the monolayer films and the interlayer collective resonance in the multilayer films have been investigated and distinguished experimentally. The influence of the post-treatment processes, including drying from different solvents and heating at a higher temperature, on the collective resonance was also evaluated. It is found that the heating treatment and washing with solvents of different surface tension is able to modify the collective resonance of Ag nanoparticles in the films.
