Over the past two decades, fiber laser technologies have matured to such an extent that they
have captured a large portion of the commercial laser marketplace. Yet, there still is a …

Upconverting nanoparticles (UCNPs) compose a class of luminescent materials that utilize
the unique wavelength-converting properties of lanthanide (Ln) ions for light-harvesting …

Materials whose luminescence can be switched by optical stimulation drive technologies
ranging from superresolution imaging,,–, nanophotonics, and optical data storage,, to …

Dioctyl terephthalate (DOTP) is the most widely used PVC plasticizer today. However, the
poor migration and volatility resistance of toxic DOTP in PVC films lead to hazards for both …

New lasers and amplifiers based on rare-earth (RE)-doped silica optical fibres need
improved spectroscopic performance. In this context, a route of interest consists of …

Ascertaining elements oxidation state, coordination, and bonding environment provides an
understanding of the parameters controlling the elements structural behavior, and in turn …

Optical, structural properties and redox were studied for Ce-bearing silicate and
aluminosilicate glasses and Ce-activated silica (SiO 2) fiber preforms, by X-ray Absorption …

We present an original experimental approach to the investigation of radiation-induced
attenuation (RIA) mechanisms in optical fiber preforms. This protocol combines thermally …

We found evidence of reduction in photo-darkening due to the presence of copper
nanoparticles (CNP) in lithium borate glasses doped with Ce3+ and Tm3+. This …

Abstract Several Ce 3+/Tm 3+-co-doped alumino-silicate glasses with various Ce 3+/Tm 3+
ratios were prepared by a sol-gel method combined with vacuum sintering. To determine …
