Luminescent inorganic-organic hybrid films based on europium-substituted heteropolymolybdate and poly(amidoamine) dendrimer

► Films based on Eu(P2Mo17)2 and PAMAM dendrimer have been prepared by LBL method. ► The films grow regularly and well-defined Eu(P2Mo17)2 nanoparticles can be achieved. ► The films exhibit the characteristic emission bands of the Eu3+ ion. ► Life time of Eu3+ is shorter in the films than in the solid.
