"Use of the polymeric theory for the description of physical and chemical properties of the liquid glass SnO-SiO2"

Sergey Krasikov
Institute of Metallurgy of Ural Branch of the Russian Academy of Sciences

Discussion of experimental data from positions of the polymeric theory of the melted silicates offered by O. A. Yesin is executed. One of its basic provisions is that oxide silicate melts consist of the linear and branched anion chains of various length which are in dynamic balance. It assumes balance between "free" ions" (O2-), one (O-) and two- coherent (O0) anions. According to the polymeric theory was the sizes of structural units and size of a surface tension and viscosity of liquid systems SnO-SiO2, SnO-SiO2-CaO, by SnO-SiO2-FeO are calculated. Results of calculations showed a satisfactory consent of settlement and skilled sizes. Thus, the polymeric model of silicate melts offered by O. A. Yesin is very perspective for the description of physical and chemical properties of stanniferous oxide melts.

"Organic lanthanides complexes for NIR OLEDs and magnetoresistance investigation"

Marco Cremona

Rio de Janeiro, RJ Brasile

The complexes of f-elements, particularly near-infrared (NIR) emitters are gaining much attention for their potential applications in optical communications, optoelectronic devices and biomedical diagnostic application. The emission from their complexes can be properly utilised in the form of OLEDs. In our laboratories Nd, Yb and Er complexes based on the various fluorinated/non-fluorinated β-diketones and O-donor neutral ligands were synthesised and fully characterised. OLEDs were fabricated and investigated using these complexes as emitting layers along with other organic layers. Moreover, a family of rare-earth quinolinate based complexes, namely tetrakis 8-hydroxyquinolinate (M[RE(q)4], with M=countercation), were used as active layers in the investigation of the spin-orbit coupling in organic magnetoresistance (OMAR) effect. Our measurements in these devices discovered a new feature in the OMAR curves evidencing the influence of the spin-orbit coupling mechanism on charge transport. These results and others will be presented and discussed in this talk.

"Boson peak investigation of glassy materials by terahertz time-domain spectroscopy"

Tatsuya Mori
Division of Materials Science Faculty of Pure and Applied Sciences
University of Tsukuba, 1-1-1 Tennoudai, Tsukuba, Ibaraki 305-8573, Japan

The boson peak (BP) has been one of the unsolved problems on glass physics, and it appears in the THz region as a universal excitation. The BP is famously detected by inelastic neutron or X-ray scattering, low-frequency Raman scattering, and low-temperature specific heat measurements. On the other hand, there have been few experimental investigations by far-infrared spectroscopy, although the technique is complemental method of Raman spectroscopy.
Recently, we showed that THz time-domain spectroscopy is suitable technique for the detection of the BP [M. Kabeya, T.M. et al., Phys. Rev. B 2016]. One of the advantages of the THz spectroscopy is the ability to determine the absolute value of the infrared light-vibration coupling coefficient (CIR).
In this lecture, we evaluate the CIR of the glassy glucose using Taraskin’s universal model [S. N. Taraskin et al., Phys. Rev. Lett. 2006]. We will see that the large absorption in the vicinity of the BP of the glassy glucose is caused by both the “light mass” effect and the disordered charge distribution.

7th International Workshop on Photoluminescence in Rare Earths (PRE'17): Photonic Materials and Devices
November 30 - December 2, 2017 | Rome, Italy

PRE’17 is the seventh event in the series of International Workshops covering a wide range of research topics concerning the properties and applications of rare-earth ions in optoelectronics and photonics. The series begun in Trento, Italy in May 2005 (PRE’05), followed by PRE’07 again in Trento, PRE’10 in Firenze (Italy), PRE’12 in Kyoto (Japan), PRE’14 in San Sebastián (Spain), PRE’16 in Greenville (USA). The next event, after the decision to move the Workshop to the odd years, will be held in Rome, Italy, at the end of 2017.

More than 600 scientists and students from more than 30 countries, in total, have attended the previous Workshops. The average size of each event, around 100 people, makes for a collegial environment where students and world experts can mingle and talk in an informal and effective way.

Over the past decade, an increasing number of luminescent materials have been reported, based on the properties of rare earth ions embedded in different matrices (crystalline, amorphous and glass ceramics; oxides, fluorides, chalcogenides, organics, ….) or contained in molecular complexes.
These materials have already been been widely employed in light sources and amplifiers, optical displays, fluorescent probes, luminescent labels, frequency converters, detectors, and so on, thus covering fields ranging from telecommunication to sensing, from medical diagnosis to energy. Despite of it, there are still increasing demands for novel functions to further extend their practical applications.

This PRE Workshop, like the previous ones, aims at providing a forum for material scientists, chemists and physicists where to debate about the state of the art and the perspectives of the photonic materials based on rare earth ions. Both fundamental photoluminescence properties and application oriented material investigations will be considered.
We would like to welcome all the interested experts from different countries in the world to PRE’17, which will be held on November 30 - December 2, 2017 in one of the most ancient and beautiful cities in the world: Roma.

Spectral sHapIng For biomedical and energy applicaTions
Tenerife, Canary Islands, Spain
November, 13-17, 2017

Important dates
Abstract submission: open from december 2016

Spectral shaping of light is an emerging route for enhancing the efficiency of various solar energy harvesting, storage and conversion processes facing the increasing demand for energy supply, from photovoltaics to photocatalysis, natural and artificial photosynthesis and solar fuels generation, where usually large parts of the solar spectrum are not efficiently utilized. Moreover the use of light in life sciences, within the well-known infrared therapeutic windows (deeper penetration and lower tissue damage) and subsequent wavelength transformation to higher or lower energies provides ground-breaking applications in photodynamic cancer therapy and bio-imaging. Interdisciplinary efforts from physics, chemistry, biology, medicine, materials science and engineering will certainly be required to overcome current challenges leading the way for spectral shaping of light to be a future key technology.

"SHIFT 2017" International Conference shows up as a cutting-edge multidisciplinary platform to gather presentations and discussions of recent achievements by leading researchers in wavelength shifting luminescence processes (quantum cutting, down-shifting, up–conversion...), as a very promising and not yet fully explored route.

Join us in warm and sunny Tenerife (Canary Islands) in November 2017 to make a significant shift to state-of-the art spectral shaping for biomedical and energy applications.

The SHIFT happens in Tenerife!
