“…These maxima were previously observed in polycrystalline YSZ and were attributed to the intraionic recombination of a lanthanide ion present as a contaminant in the samples. 35 As the peak position and spectral shape of the observed lines match those of the transition between the 1 D 2 and 3 H 4 multiplets of the Pr 3+ ion, 10,13,17,39 it is likely that in our as-grown samples praseodymium ions could be present as precursors contaminants. Actually, praseodymium doped tetragonal zirconia fibers were further produced and characterized, confirming the above assumption, as shown by the dashed line in Fig.…”

Yttria stabilized zirconia single crystal fibers doped with europium ions were developed envisaging optical applications. The laser floating zone technique was used in order to grow millimetric high quality single crystal fibers. The as-grown fibers are completely transparent and inclusion free, exhibiting a cubic structure. Under ultraviolet ͑UV͒ excitation, a broad emission band appears at 551 nm. The europium doped fibers are translucent with a tetragonal structure and exhibit an intense red emission at room temperature under UV excitation. The fingerprint transition lines between the 5 D 0 and 7 F J͑0-4͒ multiplets of the Eu 3+ ions are observed with the main emission line at ϳ606 nm due to 5 D 0 → 7 F 2 transition. Photoluminescence excitation and wavelength dependent the photoluminescence spectra confirm the existence of different Eu 3+ optical centers.

This paper describes a method for manufacturing luminescent cellulose fibers. Good optical properties of cellulose fibers under UV-C illumination were achieved by incorporating ZrO 2 (0.5 mol% of Eu 3? ) stabilized by Y 2 O 3 (7 mol%) into the fiber structure's particles. Fibers were obtained from 8 wt% cellulose solution in N-methylmorpholine N-oxide (NMMO) with the addition of a luminescent modifier in the range between 0.5 and 10 wt%. The physicochemical and mechanical parameters and the structure of these fibers were examined.

“…These phenomena are related to the electron transitions inside the 4f subshell of lanthanide ions. Methods for synthesizing nanoscaled, luminescent inorganic particles, like the sol-gel process (Fu et al 2006;Rzepka et al 2007), the Pechini method (Ninjbadgar et al 2009), high-pressure hydrothermal synthesis (Chen et al 2004;Fidelus et al 2009), chemical coprecipitation (Karbowiak et al 2005) and the solvothermal method (Ninjbadgar et al 2009;Wiglusz et al 2010) give excellent opportunities to obtain a wide range of nanoscaled powders doped with rare earth ions of various chemical structures, doping levels, and particle sizes & shapes (Karbowiak et al 2005;Wiglusz et al 2010;Pechini 1967;Lu et al 2010). These parameters influence the optical properties and chemical activity of such materials.…”

Luminescent cellulose fibers activated by Eu3+-doped nanoparticles

UV-active cellulose fibers were obtained by dry-wet method spinning an 8 % by weight acellulose solution in N-methylomorpholine-N-oxide (NMMO) modified by europium-doped gadolinium oxyfluoride Gd 4 O 3 F 6 :Eu 3? containing 5 mol (%) of the dopant. Photoluminescent nanoparticles were introduced in the in powder form into a polymer matrix during the process of cellulose dissolution in NMMO. The dependencies of emission intensity on excitation energy and the concentration of Gd 4 O 3-F 6 :Eu 3? nanoparticles in the final cellulosic products were examined by photoluminescence spectroscopy (excitation and emission). The fiber structure was studied by X-ray powder diffraction analysis. The size and dispersity of the nanoparticles in the polymer matrix were evaluated using scanning electron microscopy and X-ray microanalysis. The influence of different concentration particles (in the range from 0.5 to 5 % by weight) on the mechanical properties of the fibers, such as tenacity and elongation at break, were determined.
