Giant Pressure‐Induced Spectral Shift in Cyan‐Emitting Eu ²⁺ ‐Activated Sr ₈ Si ₄ O ₁₂ Cl ₈ Microspheres for Ultrasensitive Visual Manometry

Synthesis and Luminescent Properties of M 2 V 2 O 7 : Eu ( M 0 Sr , Ba )

A solution combustion route for the synthesis of Eu-activated M2V2O7 (M 0 Sr, Ba) and their luminescent properties have been investigated. Structure and luminescent characteristics of Sr2V2O7:Eu 3+ and Ba2V2O7:Eu 3+ nanophosphors have been studied by x-ray diffraction, scanning electron microscopy, transmission electron microscopy, fluorescence spectrometry and Fourier transform infra-red spect...

SPIN-GLASS PROPERTIES OF (Eu, Sr) S

Insulating compounds of the magnetic dilution series Eu Sr, S reveal spin glass behavior for 0.13^ x £ 0.65, similar to that in metallic alloy's*. :-7e discuss some of the experimental properties characterizing both the spin-glass state and the nature of the transition. A microscopic picture of the "frozen" state is presented based on the competition of ferromagnetic nearest neighbor and antife...

PYROELECTRIC PROPERTIES OF La-Sr-Co-O/Pb-La-Ti-O/La-Sr-Co-O HETEROSTRUCTURES

The realization of a commercially viable, thin-film uncooled pyroelectric detector has been the focus of research for several years. As part of this effort, we show that a conventional metallic electrode system (typically Pt) can be replaced with a conductive oxide such as LaxSr(1–x)CoO3 (LSCO). In addition to being crystallographically compatible with the lead-based, pyroelectric oxides such a...

Elastic properties and surface damage resistance of nitrogen-rich (Ca,Sr)-Si-O-N glasses

Giant piezoelectricity on Si for hyperactive MEMS.

Microelectromechanical systems (MEMS) incorporating active piezoelectric layers offer integrated actuation, sensing, and transduction. The broad implementation of such active MEMS has long been constrained by the inability to integrate materials with giant piezoelectric response, such as Pb(Mg(1/3)Nb(2/3))O(3)-PbTiO(3) (PMN-PT). We synthesized high-quality PMN-PT epitaxial thin films on vicinal...
