Zirconium oxide (ZrO_2) is a perspective co-dopant of rare-earth ions in silica fibers for use
in fiber lasers. ZrO_2 nanoparticles increase the solubility of rare-earth ions and enhance …

The work demonstrates for the first time a thermal regenerated grating (RG) operating at an
ultra-high temperature up to 1400° C. A new class of photosensitive optical fiber based on …

A SiO2–ZrO2 nanostructured optical fibre is fabricated using the chemical sol–gel method
associated to the drawing process; the structural and the waveguiding properties are …

The treatment of radioiodine produced from nuclear industry is a key priority. It is significant
to understand the phase evolution and microstructure transformation of the matrix in the field …

Abstract Tb 3+/Yb 3+ co-doped ZrO 2-SiO 2 nano-crystallized glasses were prepared by a
sol-gel process. The crystal structure and optical properties including down-conversion …

We demonstrate a simple, compact and low cost graphene-based mode-locked nano-
engineered erbium-doped zirconia–yttria–aluminosilicate (ZYA-EDF) glass-based fiber …

Two series of the composite silica-zirconia xerogels with various SiO2/ZrO2 molar ratios
have been prepared by the “acidic” and “basic” precipitation methods. It has been …

Y3+ (La3+), Eu3+ and Bi3+ ions co-doped sol–gel silica glasses were synthesized.
Photoluminescence spectra show that there is energy transfer from Bi3+ ions to the emission …

Abstract Bismuth silicate xBi 2 O 3·(1− x) SiO 2 xerogels, 0≤ x≤ 0.5, doped with gadolinium
have been synthesized by sol–gel method. The study aims to evidence by X-ray diffraction …

Optical and structural properties of glasses and glass-ceramics (GC) obtained by different
heat-treatment of Tb and Tb-Yb doped sol-gel derived 30ZrO2-70SiO2 materials were …
