Exploring polyoxometalate-based luminescent materials and improving their luminous performances are a challenging research subject. However, to date, relevant reports on organic-inorganic hybrid multi-nuclear rare-earth-encapsulated heteropolyoxotungstate cluster materials and their luminous performances are very rare. In this project, we plan to utilize the combination reaction strategy of the organic-water mixed solvent method (or organic solvent method ) and microwave heating method to prepare novel conjugated-electron containing functional organic ligand controlled multi-nuclear rare-earth-encapsulated heteropolyoxotungstate cluster materials and discover some key controlling factors in the reactions. The luminescent properties and luminescent dynamics of as-synthesized materials will be systematically investigated. Their luminous mechanisms will be mainly discussed and the corresponding physical models will be established. We will intensively explore the influences of the doping ratios of different rare earth ions on the luminous performances to search white-light emitting and upconversion target materials. Moreover, we will prepare the thin film materials of target materials by means of the spin-coating technology and probe their related luminescent properties. The systematic investigations on luminous performances and luminescent dynamics of conjugated-electron containing functional organic ligand controlled multi-nuclear rare-earth-encapsulated heteropolyoxotungstate cluster materials in this project will drive polyoxometalate-based materials into the field of rare earth luminescent materials and lay the research foundations for the potential applications in information display, energy-saving lighting and photoelectric detection, etc. Therefore, this study has important theory significance and potential practical application value.
