Fabrication of white luminescence composite films containing Dy-polyoxometalate and the study of their luminescence switching behaviors

Abstract

White luminescence composite films containing Dy-polyoxometalate (Dy-POM) were firstly constructed by a layer-by-layer assembly method for the realization of electrically controlled luminescence switching. Additionally, blue–white luminescence could be switched by the choice of POM structural types and control of the concentration ratio of POM/Dy-POM in solution and composite films.
