Amplification properties of Tb (III) green emission in polymeric waveguide doped with Tb–Al nanocluster

Terbium(III) and Yttrium(III) Complexes with Pyridine-Substituted Nitronyl Nitroxide Radical and Different β-Diketonate Ligands. Crystal Structures and Magnetic and Luminescence Properties

“…The spectra of 1 at room temperature and 270 K show three band maxima at approximately 18 360, 17 130, and 16 100 cm –1 . These three maxima correspond to luminescence transitions from the 5 D 4 excited state to the 7 F 5 , 7 F 4 , and 7 F 3 states of Tb(III) . Tb(III) luminescence is not visible at temperatures between 80 and 240 K. At 270 K, the intensity of the f–f transitions is significant and decreases slightly at 300 K.…”

Lanthanide luminescence for functional materials and bio-sciences

“…Some researchers have also demonstrated the feasibility of optical amplification in the visible range in polymer waveguides doped with ternary Eu III b-diketonates with phen 346,347 or Ln III -Al nanoclusters (Ln = Eu, Tb). [357][358][359] For the latter system the highest optical gain coefficients were estimated to be 0.56 and 1.28 mm À1 for Tb III -Al and Eu III -Al nanoclusters, respectively.…”

Dazzling green emission from graphene oxide nanosheet-embedded co-doped Ce3+ and Tb3+:PVA polymer nanocomposites for photonic applications

“…Rare earth metal-doped polymer-based devices have several advantages over inorganic devices in the device design and fabrication such as being light weight, having design exibility, their shape, and ease of fabrication. 1 In recent years, special attention has been focused on the luminescent rare earth ion-doped complexes for their superior properties such as narrow emission bands for high color purity, large Stokes shis, long lifetime, high quantum efficiency and good processing ability. The luminescent rare earth complexes have widely been considered as light-converting molecular devices (LCMDs) and these could open up a new class of materials in the eld of photonics.…”
