Title: | A new near-IR luminescent erbium(III) complex with potential application in OLED devices | Authors: | Martín-Ramos, Pablo Miranda, Micael D. Silva, Manuela Ramos Eusebio, M. Ermelinda S. Lavín, Víctor Martín-Gil, Jesús |
Keywords: | Erbium(III); β-Diketonate; Photoluminescence | Issue Date: | 28-Nov-2013 | Publisher: | Elsevier | Citation: | MARTÍN-RAMOS, Pablo [et al.] - A new near-IR luminescent erbium(III) complex with potential application in OLED devices. "Polyhedron". ISSN 0277-5387. Vol. 65 (2013) p. 187-192 | Serial title, monograph or event: | Polyhedron | Volume: | 65 | Abstract: | We report the synthesis and X-ray structural characterization of the new Er3+ ternary complex [Er(hd)3(bipy)] (where Hhd is 3,5-heptanedione and bipy is 2,2′-bipyridine) as well as its absorption/luminescent properties. X-ray analysis of the novel complex reveals its triclinic centrosymmetric structure with two symmetry independent complexes in the unit cell. Each lanthanide ion is surrounded by 6 oxygen atoms and 2 nitrogen atoms in a square antiprismatic geometry. The solid-state electronic absorption spectra and the luminescence spectrum show long-wavelength 4f–4f transitions which provide a potential use of the compound as a NIR emitting material in organic light-emitting devices (OLEDs). | URI: | https://hdl.handle.net/10316/26846 | ISSN: | 0277-5387 | DOI: | 10.1016/j.poly.2013.08.035 | Rights: | openAccess |
