Abstract
A novel type of inorganic hybridized ultrathin film consisting of Preyssler-type polyoxometalates K14[Na(H2O)P5W30O110] (Na-POMs) and [email protected] nanoparticles (NPs) was prepared on the solid substrates by a layer-by-layer assembly technique. The film exhibits reversible fluorescence switching behavior under control of irradiation with either UV light or visible light, which is ascribed to the selective occurrence of fluorescence resonance energy transfer between luminescent NPs and different states of photochromic Na-POMs.Keywords
