“…The deep understanding of the formation mechanisms of silver nanoparticles in host matrix is essential to achieve new silver species with proper size and shape, inter-particle distances, and volume concentration. Gold insertion was also considered as a luminescence sensitizer of rare-earth ions, such as in the Er 3+ -doped TeO 2 -ZnO system by [ 34 ]. These metallic nanoparticles were found to enhance the photoluminescence due to presence of the RE ions in the proximity of an array of silver nanoparticles.…”

This review focuses on the radiation-induced changes in germanate and tellurite glasses. These glasses have been of great interest due to their remarkable potential for photonics, in terms of extended transmission window in the mid-infrared, ability of rare-earth loading suitable with a laser, and amplification in the near- and mid-infrared or high nonlinear optical properties. Here, we summarize information about possible radiation-induced defects, mechanisms of their formation, and the influence of the glass composition on this process. Special attention is paid to laser-induced structural modification of these glasses, including possible mechanisms of the laser-glass interaction, laser-induced crystallization, and waveguide writing. It is shown that these methods can be used for photostructuring of the glass and have great potential for practical applications.

Europium Luminescence as a Structural Probe: Structure‐Dependent Changes in Eu³⁺‐Substituted Th(C₂O₄)₂·xH₂O (x = 6, 2, and 0)

Three different phases of thorium(IV) oxalate hydrate [Th(C 2 O 4 ) 2 ·xH 2 O] with different water contents, namely, the hexahydrate, dihydrate, and anhydrous phases, were prepared by thermal treatment of the as-precipitated hydrated thorium(IV) oxalates. With the change in water content, the structure changes from monoclinic (C2/m) for the hexahydrate to monoclinic (C2/c) for the dihydrate and finally to a highly disordered phase for the anhydrous state. The local coordination around the Th 4+ ions in these structures was monitored by using Eu 3+ ions as luminescent probes. The analyses of the emission spectra owing to the electric-dipole transitions (EDTs) and magnetic-dipole transitions (MDTs) of the Eu 3+ ions in the different phases revealed that the site symmetry around the Th 4+ ions decreases systematically

“…So the introduction of metal nanoparticles into the 3DOM materials doped with RE ions should be a promise approach for their luminescence enhancement. Among different metal nanoparticles, gold and silver nanoparticles have been used extensively to improve the luminescence of RE ions . In general, the LSP absorption peaks of silver nanoparticles were located at about 410 nm .…”

Novel photoluminescent films consisting of three-dimensionally ordered macroporous (3DOM) SiO 2 :Tb 3+ and Au nanoparticles were prepared by template assisted method, and their luminescence properties were investigated. The results show that Au nanoparticles have significant influence on luminescence property of SiO 2 :Tb 3+ 3DOM materials. The Au nanoparticles embedded in the skeleton of SiO 2 :Tb 3+ 3DOM materials could strongly improve their luminescence properties. The enhancement mechanism was discussed and demonstrated, which is attributed to the increasing of radiative decay rates of Tb 3+ induced by surface plasmon effects of Au nanoparticles.
