Recovery of critical metals from lamps and CRTs

2016 Electronics Goes Green 2016+ (EGG), 2016

The research activities described in this manuscript were developed within HydroWEEE projects.

Diamond-fluoride luminescent film composite.

2018 International Conference Laser Optics (ICLO), 2018

We produced luminescent diamond films with embedded europium-contained fluorides which were synthesized by different precipitation techniques. Luminescence spectra showed a narrow orange line at 612 nm. This approach has a perspective for the preparation of luminescent diamond with wanted luminescence lines.

Crystal field effect on luminescent characteristics of Europium doped orthovanadate nanoparticles

2017 IEEE 7th International Conference Nanomaterials: Application & Properties (NAP), 2017

The Eu3+impurity ions form two types of luminescent centres in the La1-xEuxVO4powder samples. Crystal field calculations and analysis of crystal field parameters have shown that for the both types of centres the Eu3+ions are under effect of the different, regular and defect, oxygen surrounding. The latter centres arise on surfaces of the particles. Increase of luminescence intensity for the samples ...


Model-based, analytical maximum-likelihood deconvolution for CZT detectors

2015 IEEE Nuclear Science Symposium and Medical Imaging Conference (NSS/MIC), 2015

An analytical response function is presented that is based on a perturbed Pearson-IV model for the peak shape and additional models for the first four moments of the distribution, mean, variance, skewness and kurtosis. The parametrisation of these moment models is acquired by using an evolutionary ensemble algorithm, delivering corresponding energy dependent functions for each of the moments. Using the ...

  • Recovery of critical metals from lamps and CRTs

    The research activities described in this manuscript were developed within HydroWEEE projects. These projects were funded by European Union in the ambit of 7 FP Work Program with the aim to develop innovative hydrometallurgical processes for the recovery of critical materials from waste electrical and electronic equipments as the fluorescent lamps and the cathode ray tubes. From recycling of them critical elements were recovered, in particular the rare earths. In the first phase of the project the hydrometallurgical processes for the recovery of yttrium was studied in laboratory and in the pilot plant. In the second phase the treatments were tested in the industrial scale, moreover the attention of researchers was focused on the implementation of the previous processes and made them more competitive increasing the fraction of recovered rare earths. Following the last experiences on laboratory scale for the recycling of lamps and cathode ray tubes were reported.

  • Crystal field effect on luminescent characteristics of Europium doped orthovanadate nanoparticles

    The Eu3+impurity ions form two types of luminescent centres in the La1-xEuxVO4powder samples. Crystal field calculations and analysis of crystal field parameters have shown that for the both types of centres the Eu3+ions are under effect of the different, regular and defect, oxygen surrounding. The latter centres arise on surfaces of the particles. Increase of luminescence intensity for the samples obtained by different methods takes place in the noted order: solid state → co-precipitation → sol gel synthesis and correlates with decreasing of the particles sizes. Correlations between grain sizes and luminescence behavior of the La1-xEuxVO4powders were studied.

  • Model-based, analytical maximum-likelihood deconvolution for CZT detectors

    An analytical response function is presented that is based on a perturbed Pearson-IV model for the peak shape and additional models for the first four moments of the distribution, mean, variance, skewness and kurtosis. The parametrisation of these moment models is acquired by using an evolutionary ensemble algorithm, delivering corresponding energy dependent functions for each of the moments. Using the relationship between the moments and the actual peak shape, this analytical equation is introduced into the Maximum-Likelihood inversion, delivering a formula for deconvolving spectra. Through the parametrisation, the technique can be tailored to any CZT detector. Without having to store a large response matrix, the analytical deconvolution can be easily deployed also on smaller devices, with less computational performance. The technique is validated on a Raspberry Pi connected to a muSPEC500 device from Ritec, featuring a 300mm3 CZT crystal. Example measurements for cesium 137Cs, cobalt 60Co, europium 152Eu and uranium 238U are deconvolved and show a significant capability of resolving peaks.

  • Numerical simulation of optical amplifiers based on Eu-doped polymer optical fibers

    We model the light amplification in Eu-doped PMMA polymer optical fibers by solving our own rate equations that describe the physical system. These equations are firstly solved in stationary state, for a constant pump power. In this case, we determine the optimum fiber length for maximum output power. We also solve the time-dependent equations to be able to launch a pulse of signal power at the input end, together with pulsed or constant pump power. The results are useful to determine the influence of some important design parameters, such as the temporal pump width or the fiber concentration.

  • Scintillation results from ionospheric modification experiment

    During September 1982 a group of U.S., West German, and Brazilian organizations evaluated the trigger mechanism of equatorial ionospheric bubbles in an ionospheric modification experiment in Brazil. The experiment involved the release of two barium chemical packages at an unstable point in the nighttime F layer. At this point, they would trigger a bubble of low ion density to rise into the middle and upper F regions. Following the release of the barium, an aircraft equipped with a UHF satellite receiver was flown in the shadow of the bubble. It mapped the growth of the resulting irregularities from their initial appearance until they grew to a width of 100 km or more. The experiment demonstrated that a bubble could be triggered by proper placement of the barium ions and that the resultant irregularities would have the appearance of naturally triggered equatorial ionospheric irregularities.

The results of a series of experiments aimed at characterising Eu/sup 2+/ doped fibres and comparing their behaviour to germanosilicate fibres are reported.<>

  • Investigation of the Magneto-Optical Properties of Europium Containing Fluorides

    The magneto-optical characteristics of the europium fluoride crystal were measured. They are 100% -55% higher than the corresponding values for the popular TGG crystal. Taking into account better spectral characteristics in the mid-IR range and good thermo-optical characteristics, it can be concluded that the use of europium containing fluorides is promising in the development of Faraday isolators for mid-IR lasers.
