Thermostable Eu(III)-nanorod luminophores with effective photosensitized energy transfer

摘要: Abstract The thermostable Eu(III)-doped nanorod aggregates composed of luminescent Eu(III) complexes and diphenylphosphinic acids (DPP) are reported. Prepared Eu(III)-nanorod [Eu(hfa) x (TPPO) y z ] n (hfa: hexafluoroacetylacetionate, TPPO: triphenylphosphine oxide), Eu(III)-nanoparticle , standard Eu(III)-nanoparticles [Eu(DPP) were characterized using X-ray diffraction (XRD) transmission electron microscopy (TEM) measurements. decomposition temperatures for thermogravimetric analysis (TGA) found to be over > 500 °C. Photosensitized luminescence was successfully observed excited at the specific π–π* transition band organic hfa ligands (λ = 340 nm), which is similar inter-ligand charge transfer (ILCT) in solid-state, observed. photosensitized energy efficiency estimated 91%. In this study, aggregate luminophore DPP joint compounds demonstrated.
