Abstract
There is provided a photofunctional laminated article being excellent in various photofunctionalities, particularly an intensity of light emission, light emitting efficiency and further fluorescence life and light amplifying property. The photofunctional laminated article comprises the transparent substrate (L0), the photofunctional layer (L1) comprising the fluorine-containing polymer (A) and the rare earth metal compound (B) and being formed on the substrate (L0) and the low refractive index layer (L2) formed on the photofunctional layer (L1), and when refractive indices of each layer are assumed to be n(L0), n(L1) and n(L2), the following equation: n(L0)≧n(L1)>n(L2) is satisfied.
