Luminescent Layer by Layer Thin Films Based on Polyoxometalate and Poly(amidoamine) Dendrimer

Abstract:

Ultrathin multilayer films containing polyoxometalate (POM) K₁₁[Eu(PW₁₁O₃₉)₂] (Eu(PW₁₁)₂) and poly(amidoamine) (PAMAM) dendrimer were prepared using layer-by-layer (LBL) assembly method in the present work. The stable multilayer films were assembled by alternate adsorption of negatively charged POM and positively charged PAMAM from their aqueous dispersions. The growth of the muhilayer films is regular．The proposed novel immobilized method exhibited good stability and the photoluminescent behavior of films at room temperature was investigated to show the Eu³⁺ charaeteristic emission pattern，which is important for practical application.
