Monitoring the orientation of rare-earth-doped nanorods for flow shear tomography
Jongwook Kim, Sebastien Michelin, Michiel Gilberts +9
Rare-earth phosphors exhibit unique luminescence polarization features originating from the anisotropic symmetry of the emitter ion's chemical environment. However, to take advanta…
Electric field induced birefringence in non-aqueous dispersions of mineral nanorods
Alexis de la Cotte, Pascal Merzeau, Jong Wook Kim +4
Lanthanum phosphate (LaPO4) nanorods dispersed in the non-aqueous solvent of ethylene glycol form a system exhibiting large intrinsic birefringence, high colloidal stability and th…
Surface conductivity of DR1-functionalized organic-inorganic sol-gel materials
J. -A. Reyes-Esqueda, A. Franco, M. Bizarro +7
In recent years, in looking for an important photorefractive application, several studies on electro-optic and photoconductive sol-gel responses have been done. A very important ef…
Effect of chromophore-chromophore electrostatic interactions in the NLO response of functionalized organic-inorganic sol-gel materials
J. Reyes-Esqueda, B. Darracq, J. Garcia-Macedo +7
In the last years, important non-linear optical results on sol-gel and polymeric materials have been reported, with values comparable to those found in crystals. These new material…
Non-monotonic field-dependence of the ZFC magnetization peak in some systems of magnetic nanoparticles
R. Sappey, E. Vincent, N. Hadacek +3
We have performed magnetic measurements on a diluted system of gamma-Fe2O3 nanoparticles (~7nm), and on a ferritin sample. In both cases, the ZFC-peak presents a non-monotonic fiel…
Anomalies in the Relaxation of Small Magnetic Particles at Very Low Temperatures
R. Sappey, E. Vincent, J. Hammann +3
The magnetization relaxation rate of small gamma-Fe2O3 particles dispersed in a silica matrix has been measured from 60 mK to 5 K. It shows a minimum around 150 mK, that can be dis…
