Transparent Er3+-activated lead fluorogermanate glass ceramics
(2003-12-01)
Transparent glass ceramics containing β-PbF2:Er 3+ nanocrystals were obtained through appropriate thermal treatments of a glass of molar composition 60PbGeO3-10PbF2-30CdF 2 doped with 0.5 mol% Er3+. Their optical properties, ...

Thermal baths as quantum resources: More friends than foes?
(IOP Publishing, 2015-11-06)
In this article we argue that thermal reservoirs (baths) are potentially useful resources in processes involving atoms interacting with quantized electromagnetic fields and their applications to quantum technologies. One ...
Three-dimensional trapping of light with light in semiconductor planar microcavities
(American Physical Society, 2019-05)
When light is confined in all three directions and in dimensions of the order of the light wavelength, discretization of the photon spectra and distinctive phenomena occur, the Purcell effect and the inhibition of emission ...
Luminescent Eu3+ doped Al6Ge2O13 crystalline compounds obtained by the sol gel process for photonics
(2018-01-01)
We synthesized pure and Eu3+ doped Al6Ge2O13 samples by an easy and low-cost sol-gel route using the GeO2, Al(NO3)3·9H2O and Eu(NO3)3·6H2O as precursors, tetramethylammonium hydroxide and ethanol as solvents. The Al6Ge2O13 ...
Photophysical properties of blue-emitting silicon nanoparticles
(American Chemical Society, 2009-08)
Silicon nanoparticles with strong blue photoluminescence were synthesized by electrochemical etching of silicon wafers and ultrasonically removed under N 2 atmosphere in organic solvents to produce colloids. Thermal treatment ...
2FHL J0826.1-4500: Discovery of a Possible Shock-Cloud Interaction on the Western Edge of the Vela Supernova Remnant
(IOP Publishing, 2019-01)
We report on the investigation of a very high-energy, Galactic γ-ray source recently discovered at >50 GeV using the Large Area Telescope on board Fermi. This object, 2FHL J0826.1-4500, displays one of the hardest >50 GeV ...
