Broad excitation of rare earth dopants in chalcogenide glasses
… a novel broad band excitation effect in rare earth-doped chalcogenide glasses. Photoluminescence excitation (PLE) bands with a width of ~450 nm have been observed which efficiently excite a number of rare earth emission lines. This effect is attributed to the absorption of excitation …

Broad Band Excitation of Rare-Earth Dopants in Chalcogenide Glasses
… a novel broad bands excitation effect in rare earth-doped chalcogenide glasses. Photoluminescence excitation (PLE) bands with a width of $\sim$450 nm have been observed which efficiently excite a number of rare earth emission lines. This effect is attributed to the absorption of excitation …

Nanostructured materials for photovoltaics and microwave electronics: methods and applications
… improvements by introducing trivalent rare earth dopants (Pr, Nd, Sm, Gd, Er and Yb) into the “standard” TiO2 beads. Rare earth ions’ dimension was found to affect TiO2 average crystallites size through nucleation control and ultimately electron recombination lifetime through TiO2 …

The sol-gel synthesis of anti-stokes luminescent glass materials
… are described. The literature has shown that rare earth doped oxide glasses, whilst chemically durable and relatively easy to manufacture, have weak anti-Stokes emissions, whereas rare earth doped fluoride materials have considerably improved anti-Stokes luminescence but are less chemically …

Power scaling and nonlinear conversion in fiber-based sources at novel wavelengths
… to specific wavelengths regions by typical used rare-earth dopants such as ytterbium (Yb) around 1 µm, erbium (Er) with emission around 1.55 µm, thulium (Tm) with a gain emission from 1.7 to 2.0 um, and holmium (Ho) with an emission from 2.05 to 2.1 µm. Extending the wavelength range of …

Sustainable Development of New Phosphors for Photonics Applications
… the mechanism being also active among co-doping rare earths (from Tb3+ to Eu3+), allowing further tuning of the emission properties. The second year centred on optimizing the mechano-luminescent properties of CaZnOS: Tb using microwave-assisted synthesis (MAS) method. The results were compared …
