We focus on the development of new silicate phosphors for a white LED. In the europium doped silicate system, four LED phosphor candidates—Li2SrSiO4:Eu, Ba9Sc2Si6O24:Eu, Ca3Si2O7:Eu and Ba2MgSi2O7:Eu were found. Luminescent properties under near UV and visible excitation were investigated for the new Eu2+ doped LED silicate phosphors. These new phosphors have a relatively strong absorption band...

The biocompatibility of multifunctional nanomaterials is very important for their clinical applications. Herein, the hexagonal crystal Eu-doped GdPO4 nanorods (NRs) in the template of silk fibroin (SF) peptides are successfully synthesized via a mineralization process. The sizes of the Eu-doped GdPO4 NRs with SF peptides (SF-NRs) are ∼150 nm in length and ∼10 nm in diameter. The Eu-doped SF-NRs...

In this article, European public finances are analyzed by focusing on the EU budget and the influence of the EU on member states’ taxes and spending. Starting from the economic theory of federalism, the chapter surveys the development of EU revenue, spending and off-budget activities, discusses the redistributive impact of the EU budget on member states, budgetary decision-making procedures and...

Explaining and understanding the external role of the European Union (EU) has been an under-researched aspect of theorizing about the EU. This article analyses the motivations and methods through which the EU and its member states attempt to regulate contact with international actors. Examining the EU’s contact with the Association of South East Asian Nations (ASEAN) and more recently the Asia–...

Europe has long defied GATT/WTO rules on agricultural trade during adjudication of trade disputes, but agreed to major reforms of its agricultural policies in the Uruguay Round. Such variation in liberalization outcomes raises questions about when nations will delegate to international institutions and how EU institutions influence its trade policy. This paper focuses on the policy process to e...

The KMg4(PO4)3:Eu(2+) phosphor was prepared by the conventional high temperature solid-state reaction. The crystal structure, luminescence and reflectance spectra, thermal stability, quantum efficiency and the application for N-UV LED were studied respectively. The phase formation and crystal structure of KMg4(PO4)3:Eu(2+) were confirmed from the powder X-ray diffraction and the Rietveld refine...

Herein we describe the investigation of cubic spherical submicron particles of non-doped Y2O3 and Y2O3 doped with Eu 3+ in a transmission electron microscope (TEM) equipped with a spectrometer to detect cathodoluminescence from individual particles. Each submicron particle was made up of nanometre sized crystals. We found that these crystals showed a broad emission band at 353 nm upon bombardme...
