Eu ions-doped cubic mesoporous silica thin films with a thickness of about 205 nm were prepared on silicon and glass substrates using triblock copolymer as a structure-directing agent using sol–gel spin-coating and calcination processes. X-ray diffraction and transmission electron microscopy analysis show that the mesoporous silica thin films have a highly ordered body-centered cubic mesoporous...

Recently, European Union (EU)/European Economic Area (EEA) countries have witnessed an unprecedented volume of migration, with 1,046,599 migrants arriving in Europe in 2015 [1]. Of these migrants, most have Syrian, Afghan or Iraqi nationality, and they mainly arrived via the eastern Mediterranean route. Before the increase in migration in 2015, the EU/EEA area was already an attractive destinat...

We investigate photoluminescence of Eu-related emission in a GaN host consisting of thin layers grown by organometallic vapor-phase epitaxy. By comparing it with a reference sample of Eu-doped Y₂O₃, we find that the fraction of Eu(3+) ions that can emit light upon optical excitation is of the order of 1%. We also measure the quantum yield of the Eu-related photoluminescence and find this to rea...

The 2D isostructural lanthanide-organic frameworks [Ln(4-SBA)(IP)OH] · 1.5H2O (Ln = Sm 1, Eu, 2 Gd3 and Tb 4 ; 4-SBA = 4-sulfobenzoate and IP = 1H-imidazo[4,5-f][1,10]-phenanthroline) display different luminescent behavior. White light emission was realized by introducing single dopant Eu(III) and codopants Eu(III)/Gd(III) or Eu(III)/Tb(III) into the Sm(III) framework for the first time.

The modernisation of the existing EU framework for personal data protection is necessary in order to fulfil the obligation incumbent on the EU legislator by virtue of Article 16 TFEU. It is also an essential element of delivering effective protection of the fundamental rights of EU citizens to privacy and personal data protection set out in Articles 7 and 8 of the Charter of Fundamental Rights ...

We investigate high-pressure induced phase transitions of YF3 and Eu-doped YF3 (YF3:Eu(3+)) by using the angular dispersive synchrotron X-ray diffraction technique at room temperature. It is found that the starting orthorhombic phase transforms into a new high-pressure phase which is identified as hexagonal structure in both YF3 and YF3:Eu(3+). The high-pressure structure of YF3 and YF3:Eu(3+) ...

This report aims to provide an overview of the intensity of work and work satisfaction in Korea by comparing the first Korean Working Conditions Survey with the results of the fourth European Working Conditions Survey in 2005. According to the comparison, Korean workers work longer hours than workers in the majority of EU countries. However, work intensity in the EU 27 was 1.5 times stronger th...

Does Joining the EU Make You Happy? Evidence from Bulgaria and Romania* We examine the effect of joining the European Union on individual life satisfaction in Bulgaria and Romania in the context of the 2007 EU enlargement. Although EU membership is among the most important events in Bulgaria and Romania’s modern histories, there is no evidence on how it affected the subjective well-being of ord...

In the title one-dimensional coordination polymer, [Eu(C(8)H(5)N(2)O(2))(3)](n), the Eu(III) ion is eight-coordinated by the carboxyl-ate O atoms of six ligands in a distorted monocapped penta-gonal-bipyramidal geometry. The ligands link Eu(III) ions, forming helical chains parallel to the c axis, with Eu⋯Eu separations of 4.0678 (11) Å. The chains are further inter-connected by N-H⋯N hydrogen ...
