Opal Template

Mn2+-doped Zn2SiO4 inverse opals were synthesized by sol-gel technique combined with the self-assembly of the opal template. Zn2SiO4:Mn2+ precursors were infiltrated into the interstices of the opal template assembled by polystyrene spheres. The polystyrene template was removed by calcining and nanocrystals of Mn2+-doped Zn2SiO4 were obtained in the void of opal template. The inverse opals show photonic crystal behavior and emit yellow light initially with the luminescent peak at 562 nm corresponding with the fact that β-phase is the dominant phase for nanocrystals less than 30nm. As the β-phase transformed to α-phase with the gradual increase of treating temperature and the growth of the crystal, the luminescence from Zn2SiO4:Mn2+ phosphors change from yellow to green.

Enhanced Luminescence

Two dimensional nanophosphors of high quality play an important role in the miniaturization and intelligentization of opto-electronic components. In this present work, ultra-large (30μm) single crystals of (Y0.95Eu0.05)2(OH)5NO3·nH2O layered rare earth hydroxide (LRH) with a hexagonal shape have been synthisized via autoclaving the rare-earth nitrate/NH4OH reaction system in the presence of ammonium nitrate (NH4NO3). The nitrate ions, existing in the interlayer gallery of layered rare earth hydroxide, exhibit facile exchanges with oleate anions by hydrothermal anion exchange. Furthermore, the interlayer distance can thus be expanded from ~0.9 nm for the pristine LRHs to ~3.60 nm for the intercalated ones, which are then efficiently delaminated into unilamellar nanosheets with a lateral size of 10μm and a thickness of ~1.50 nm. The obtained nanosheets are single crystaline. Highly [11 oriented, dense (Y0.95Eu0.05)2O3 phosphor films with excellent optical transparency and a greatly enhanced luminescence intensity have been constructed via self-assembly of ultra-large unilamellar LRH nanosheets, followed by proper annealing.

Two new polymeric MnII complexes, {[Mn(1,2-BDC-F4)(H2O)3](EtOH)}n (1) and [Mn(1,2- BDC-F4)(H2O)2(DMF)]n (2), have been prepared from the reaction of MnII acetate with 3,4,5,6- tetrafluoro-benzene-1,2-dicarboxylic acid (1,2-H2BDC-F4) using different solvents, and characterized by elemental analysis, IR spectroscopy, thermogravimetric (TG) analysis, and single-crystal Xray structure analysis. Both complexes crystallize in the triclinic space group P1̄ and have similar one-dimensional double chain structures, consisting of a unique arrangement of 8-membered and 14- membered rings. The effects of solvent as ligand and/or guest on the self-assembly processes of the supramolecular networks and on their photoluminescence properties in the solid state are discussed.
