In this work, photoluminescent properties of Ru (bpy)32+ incorporated in cellulose nanofiber (CNF) film was investigated by comparing with those in polyvinyl alcohol (PVA) and polyacrylic acid (PAA) films. In the polymer films, the luminescence intensity of Ru (bpy)32+ was high and λmax of luminescence spectra was blue-shifted compared with those in aqueous solution. The high luminescence intensity was also observed in cellulose nanofiber (CNF) films but the spectrum was red-shifted. Luminescence decay measurement showed that the decays in polymer films were exponential and the lifetimes were far longer than that in aqueous solution. On the other hand, in CNF films, the decays were composed of fast and slow ones. The luminescence properties of Ru (bpy)32+ in CNF films were discussed based on the stabilization of excited state and the dispersibility of Ru (bpy)32+ in the films.
