The obtained systems were characterized with elemental analysis, IR, TGA/DTG and XRD techniques. Photoluminescence properties were investigated and processes of energy transfer and sensitization were studied. Monochromatic emissions of obtained polymeric systems enabled their potential applications in multicolor displays because of the primary colors emitted by TR3+: red (Sm3+ and Eu3+), blue (Gd3+) and green (Tb3+). The polymer matrix performs an essential role in the luminescent sensitization processes for systems containing Sm3+, Eu3+, Gd3+ and Tb3+, therefore the overall systems act as Light Conversion Molecular Devices (LCMDs).Resumo IPEN-doc 14452 Photoluminescence of aluminium phosphate glasses doped with rare earths2007 - STEFANI, ROBERVAL; RODRIGUES, LUCAS C.V.; CARVALHO, CARLOS A.A.; KAI, JIANG; SANCHES, MARCO A.; FELINTO, MARIA C.F.C.; BRITO, HERMI F.Resumo IPEN-doc 16393 Tuneable luminescence in multicolour films2010 - KAI, JIANG; NUNES, LUIZ A.O.; FELINTO, MARIA C.F.C.; MALTA, OSCAR L.; BRITO, HERMI F.Trivalent Rare Earth (RE3+) β-diketonate complexes and polymethylmetacrylate (PMMA) have been widely employed in the productions of luminescent materials. In this work, preparation, characterization and photoluminescence studies for a series of stand-free polymer thin films incorporating RE3+-β-diketonate complexes into PMMA were reported. The PMMA matrix not only immobilizes the luminescent RE3+ species via physical and chemical interactions, but also operates as co-sensitizer and enhances the characteristic monochromatic emissions arising from the 4f–4f intraconfigurational transitions of the RE3+ ions. Furthermore, it was observed colour-tuneable luminescence with the polymeric systems. Therefore, they are potentially attractive for the production of advanced photonic applications such as multicolour anti-falsification optical markers, λex.= 254 nm full range UV sensors etc. Moreover, the observation of intermolecular energy transfer from the emitter level (5D4) of Tb3+ ions to the triplet state (T1) of the Eu3+ species was unprecedented in literature.Resumo IPEN-doc 16065 Energy transfer in tunable luminescent multicolor PMMA films doped with REsup(3+)-'beta'-diketonate complexes2010 - BRITO, H.F.; KAI, J.; FELINTO, M.C.F.C.; NUNES, L.A.O.; MALTA, O.L.Resumo IPEN-doc 18723 Low temperature synthesis of Rsub(2)Osub(3):Eusup(3+) (R: Y, Gd and Lu) nanophosphor using trimellitic acid precursors2012 - RODRIGUES, LUCAS C.V.; KAI, JIANG; FELINTO, MARIA C.F.C.; HOLSA, JORMA; BRITO, HERMI F.; SILVA, IVAN G.N.
