Abstract

A new kind of hybrid self-assembled film was obtained by means of alternating deposition of the polyoxometalate (POM), K₁₃[Eu(SiW ₁₁O₃₉)₂], and polyacrylamide (PAA) on the 3-aminopropylsilanized precursor film. The experimental results showed that the polyanions were successfully incorporated into the self-assembled multilayers of the polyacrylamide. The scanning electron microscopy (SEM) was taken to study the surface morphology of the film. The X-ray photoelectron spectra (XPS) verified that the polyoxometalates were incorporated into the multilayer films with a certain adsorption interaction. The effects of the polyacrylamide on the luminescence of the polyoxometalate were discussed in detail. The luminescence spectra showed that the energy was transferred from the ligands to the Eu ³⁺ ions in the self-assembled films.
