1.53 μm photoluminescence from ORMOSIL films doped with erbium complexes

Novel Stoichiometrically Erbium−Ytterbium Cocrystalline Complex Exhibiting Enhanced Near-Infrared Luminescence

“…ErCl 3 ·6H 2 O or YbCl 3 ·6H 2 O was obtained from Er 2 O 3 or Yb 2 O 3 by dissolution in hydrochloric acid and the subsequent careful removal of the the solvent. Monometallic organic complexes and the Er−Yb cocrystalline organic complex, Ln(HFA) 3 (TPPO) 2 (Ln = Er, Yb, or Er 1/ 2 Yb 1/2 ), were synthesized through the general procedure described in the ref , confirmed by elemental analysis and FTIR. Here, the procedure for the preparation of Er 1/2 Yb 1/ 2 (HFA) 3 (TPPO) 2 was described as an example.…”

Near-infrared photoluminescence of erbium tris(8-hydroxyquinoline) spin-coated thin films induced by low coherence light sources

“…Some organolanthanides have shown electroluminescence in the near-infrared range. [10][11][12][13][14][15][16] Among the different erbium organic compounds analyzed in literature, 7,[17][18][19] erbium tris͑8-hydroxyquinoline͒ ͑ErQ 3 ͒ is the most interesting organic infrared emitter because it has shown the highest photoluminescence [20][21][22] and electroluminescence [23][24][25] intensities centered at 1525 nm; this corresponds to the low loss third window wavelength range used in standard optical communications. ErQ 3 is a small molecule; for this reason, organic light emitting diodes based on such a compound can be manufactured using vacuum processing techniques, such as thermal evaporation.…”

Electrospinning preparation and photophysical properties of one-dimensional (1D) composite nanofibers doped with erbium(III) complexes

“…Er 3 + ion shows characteristic emission centered at 1535 nm via an intra-4f shell transition from its first excited state ( 4 I 13/2 ) to the ground state ( 4 I 15/2 ), which corresponds to the minimum loss transmission window of quartz fibers in the optical communication network [4]. Great effort is devoted to the erbium(III) organic complexes [5], because the full width at half maximum (FWHM) of any Er-doped inorganic material is relatively small [6].…”

“…Such lanthanide chelates can protect the metal ions from vibrational coupling and increase the light absorption crosssection via ''antenna effects'' [7,8]. Recently, great attention has been paid to the potential materials for fabricating low-cost optical amplifiers, such as Er(III) complex doped sol-gel, mesoporous and polymer materials [4,9,10]. However, the doped amount is low due to poor solubility of Er(III) complex in precursor of gel or mesoporous materials, and it is difficult to obtain continuous super long, flexible and uniform diameter fibers using them as matrices.…”
