The near-infrared emission from calcium boroaluminate (CABAL) glasses codoped with Er3+ and Tm3+ has been investigated. It is shown that by controlling the [Tm]/[Er] concentration ratio a fairly flat emission with a bandwidth of 370 nm can be achieve

The formation and optical response of VOx nanoparticles embedded in amorphous aluminium oxide (Al2O3) thin films by pulsed laser deposition is studied. The thin films have been grown by alternate laser ablation of V and Al2O3 targets, which has resul

Pulsed laser deposition has been used to prepare nanostructured rare-earth-doped films. Alternate deposition from the host (Al2O 3) and dopant (Er, Yb) targets has been used to obtain artificially structured films in which the rare-earth ion-ion sepa

The sensitization of the infrared luminescence of Er ions by Si clusters is studied in oxide films derived from tetraethoxysilane and triethoxysilane gels, doped chemically or by ion implantation with Er and/or Si. No quenching of the luminescence by

Silicon nanoclusters formed in triethoxysilane during annealing at temperatures above 900°C are used for increasing the excitation cross section of Er atoms. A stronger sensitization of the Er luminescence is observed, for a given Er concentration,

Er-doped amorphous Al2O3 films produced by alternate pulsed laser deposition show a weak Er PL emission at around 1.54 μm, the lifetime being of the order of 0.1 ms. On thermal annealing treatments up to 850 °C, the intensity increases and lifetime

The thermally stimulated currents (TSC) processes induced by ultraviolet light and x-ray irradiation at low temperature in oxidized magnesium-doped aluminum oxide single crystals has been studied between 80 and 300 K. It has been found that the main
