“…[13,14] The REQ 3 spectra are dominated by the absorption from the organic ligands, due to the fact that the absorption coefficients of typical organic molecules are orders of magnitude higher than those of the rare earth ions. [3] As with the FTIR spectra, the UV-vis spectra of the REQ 3 s are very similar to each other, with the largest absorption peak occurring at 263 nm, and the second largest at 380 nm. A third absorption peak at 320 nm is most readily visible for DyQ 3 but clearly present for all the other REQ 3 s. The REQ 3 spectra correspond well to that of AlQ 3 , which shows the same two main features with some structure around 325 nm.…”

“…The efficiency of energy transfer from the ligand triplet to the to rare earth ion is directly proportional to the spectral overlap of the donor emission and the acceptor absorption. Figure 4 shows the absorption spectra of YbCl 3 and ErCl 3 showing the RE 3+ absorption peaks. For Er 3+ , states energetically resonant with the ligand triplet state are present, however no such overlap is present for Yb 3+ .…”

“…The presence of an organic chromophore improves the efficiency of the rare earth light emission. Optically generating rare earth luminescence directly is difficult due to the small absorption coefficients of the lanthanide ions, however the absorption coefficients of organic chromophores is orders of magnitude higher, [3] and when excited it can transfer its energy to the rare earth, often called the antenna effect. [4] Numerous rare earth chelates that have been synthesized have shown photo-and electroluminescence in the visible and in the infrared.…”

We report a study of a series of heavy rare earth tris‐8‐hydroxyquinolines (REQ3s), using UV‐visible absorption spectroscopy, infrared absorption spectroscopy, and photoluminescence (PL) measurements. We show that the heavy REQ3s are all chemically similar to each other and to aluminium tris‐8‐hydroxyquinoline, at least in terms of the ligand behavior. Characteristic rare earth 4f–4f luminescence is only observed for ErQ3 and YbQ3 due to the relatively low energy of the ligand triplet state. We show that a triplet transfer mechanism cannot be responsible for the observed Yb 4f–4f luminescence observed in YbQ3. Instead, an internal chemiluminescent process is shown to be energetically favorable. The thin film PL spectra of all the heavy REQ3s are dominated by triplet emission, except for that of ErQ3, for which transfer to the Er3+ ion represents an efficient alternative. The PL spectra of powder samples, which would be expected to consist of approximately equal amounts of both isomers, are dominated by singlet emission. This is in contrast to the results from the thin films, and suggests that the isomer which predominates in the thin films has a much higher intersystem crossing rate than the other isomer.

“…Functionalization of the complex with chromophores has been reported to lead to a significant increase in the excitation efficiency. As an example, in fluorinated polycarbonate polymer waveguides doped with a Nd 3+ complex an increase in the excitation efficiency by a factor of 10 4 was observed after functionalization with a lissamine chromophore [233], whose chemical formula is shown in Fig. 29a.…”

Solid-state organic amplifiers and lasers are attractive for hybrid integration due to their compatibility with different material platforms, straightforward processing, and possibility to optimize easily their optical and electronic properties by molecular engineering. Advances in the gain medium design and synthesis in combination with new resonator architectures led to tremendous improvements in temporal and spectral properties, lifetime stability, gains produced and operating threshold powers, which triggered interest in their use for a broad range of integrated photonic applications. In this contribution, the current state-of-the-art in the field of organic solid-state amplifiers and lasers is reviewed from the aspects of fabrication technology, gain materials, and device performance. Furthermore, examples of the progress of this technology from a laboratory curiosity to one that demonstrates practical integrated photonic applications are highlighted. An outlook is also provided on research areas and applications that are likely to shape further developments of this technology. (Figure reprinted from [296],

“…Chromophores can be used that absorb at longer wavelengths and consequently have larger maximum extinction coefficients. We have already mentioned different classes of sensitisers: well-known organic dyes [18,46,47], metal indicators [7,16], organometallics [25] and porphyrins [14,[48][49][50]. Many visibly absorbing organic and organometallic chromophores can be sensitisers for lanthanide luminescence, provided that the energy of their lowest excited (triplet) state is sufficiently high to transfer energy efficiently and irreversibly to the accepting lanthanide ion.…”

The use of near-infrared (NIR) light in bioanalytical detection and biological imaging presents certain advantages over UV-visible light in terms of penetration depth, reduction of background signals and decreased phototoxicity. Under suitable conditions, complexes of ytterbium(III)-, neodymium(III)-and erbium (III)-containing organic chromophores may display relatively bright NIR luminescence upon excitation with visible light. This contrasts with the more commonly studied visibly luminescent europium(III) and terbium(III) complexes, which generally need UV or blue light for excitation. We discuss the current knowledge on NIR luminescence of lanthanide complexes (including holmium(III), praseodymium(III) and thulium(III)) in solution. It is suggested that among the NIR luminescent lanthanide complexes, ytterbium(III) complexes are likely to be the most promising candidates for biophotonic applications. The study of NIR luminescence and its application in bioanalytical detection are enabled by progress in detector and light source technology, which are also addressed. Recent developments in lanthanide-based NIR luminescent materials, including complexes and doped nanoparticles, are discussed in the light of their potential for bioanalytical application.
