The 1.5 μm fluorescence shape and lifetime of Er3 + -activated tellurite glasses have been investigated. The measures on bulk system have been compared with those obtained on powders, showing that the self-absorption effect broadens the emission spectrum and lengthens the lifetime. It has been demonstrated that the bandwidth and lifetime measurements depend on the absorption coefficient α(λ) and on the distance d between the focused exciting laser beam and the exit face of a bulk glass sample. The ...

70SiO2–30HfO2 mol% planar waveguides, doped with Er3+ with concentrations ranging from 0.3 to 2 mol% were prepared by sol–gel route, using dip-coating deposition on vitreous-SiO2 substrates. Infrared-to-visible upconversion emission, upon excitation at 980 nm, has been observed for all the samples. The upconversion results in green, red and blue emissions. The investigation of the upconversion dynamic as a function of the Er3+ concentration and excitation power, show that processes such as excited ...

Propagation losses of about 1 dB/cm were measured at 632.8 nm. When pumped with 987 or 514.5 nm continuous-wave laser light, the waveguides show the I413/2→I415/2 emission band with ...

Spinal and bulbar muscular atrophy (SBMA), known as Kennedy disease (KD), is a slowly progressive adult-onset X-linked neuromuscular disorder with no effective treatment. It is characterised by progressive limb and bulbar muscle weakness, associated with metabolic and endocrine alterations.1 2 SBMA is caused by the expansion of a CAG repeat in exon 1 of the androgen receptor ( AR ) gene; more than 37 repeats are pathogenic.1 While the genetic test is diagnostic, biomarkers would aid the initial differential ...

Timed Failure Propagation Graphs (TFPGs) are used in the design of safety-critical systems as a way of modeling failure propagation, and to evaluate and implement diagnostic systems. TFPGs are a very rich formalism: they allow to model Boolean combinations of faults and events, also dependent on the operational modes of the system and quantitative delays between them. TFPGs are often produced manually, from a given dynamic system of greater complexity, as abstract representations of the system behavior ...

Proximal sensing is fundamental to monitor the spatial and seasonal dynamics of ecosystems and can be considered as a crucial validation tool to upscale in situ observations to the satellite level. Linking hyperspectral remote sensing with carbon fluxes and biophysical parameters is critical to allow the exploitation of spatial and temporal extensive information for validating model simulations at different scales. In this study, we present the WhiteRef, a new hyperspectral system designed as a ...

Ultra-transparent glass–ceramics activated with thulium ions were fabricated employing different heat treatments of precursor oxy-fluoride glass. The spectroscopic properties of the thulium ions, studied through UV–Vis–NIR absorption and luminescence spectroscopy, showed that most of the active ions were embedded in the crystalline phase. The size of nucleated nanocrystals, controlled by the temperature and time of annealing and measured by low-frequency-Raman spectroscopy, was found to range from ...

Er3+-doped glasses have been a subject of great interest in the recent years for their application in the areas of guided wave optical amplifiers and lasers. Oxide–glass matrices, in particular, offer the advantage of relatively simple fabrication processes—both for bulk glasses and optical fibers—and have demonstrated quite good properties in the 1.5 μm wavelength band. Here we present some results we have obtained in the development of different silica-based glasses and in their application to ...

Seven years of continuous eddy covariance measurements at an alpine meadow were used to investigate the impacts of climate drivers and ecosystem responses on the inter-annual variability (IAV) of the net ecosystem exchange (NEE). The annual cumulative value of NEE was positive (source) in 2003, 2005 and 2009 (50, 15 and 112 g m−2 respectively) and negative (sink) in 2004, 2006, 2007 and 2008 (29, 75, 110 and 28 g m−2 respectively).

Silicate glasses remain the most investigated systems for optical planar waveguides, since they offer a reasonable solubility for rare-earth ions, they are transparent in the near-infrared–visible region and they are compatible with integrated optics (IO) technology. In the last decade, various technologies have been employed for the fabrication of silica (SiO2)-based IO components and a broad variety of silicate glass systems have been investigated. Besides the SiO2–titania (TiO2) system, which has ...
