Synthesis and structural investigation of the Eu 1–x Bi x VO 4 scheelite phase: X-ray diffraction, Raman scattering and Eu 3+ luminescence

Jean‐Luc Blin、Annick Rubbens、F. Wallart 等 4 位作者1996-01-01Journal of Materials Chemistry

A previous investigation of EuVO4–BtVO4 binary system has indicated the existence of a solid-solution of Eu1–xBixVO4 up to x= 0.60, with a zircon-type structure. In this work we have reinvestigated the synthesis conditions, thus extending the upper limit to x= 0.74. X-Ray diffraction techniques associated with Raman a…

Surface-field induced organisation at solid/fluid interfaces

Stephen D. Evans、H. Allinson、N. Boden 等 4 位作者1996-01-01Faraday Discussions

Self-assembled monolayers of alkanethiol derivatives have been used to control the anchoring of nematic films of alkylcyanobiphenyl (nCB) liquid crystals. Variation of the surface field, via the ω-functional group presented at the liquid crystal interface, has allowed us to explore both orientational wetting and ancho…
