We observe the two- and three-pulse photon echo emission from a scattering powder, obtained by grinding a Pr3+:Y2SiO5 rare earth doped single crystal. We show that the collective emission is coherently constructed over several grains. A well defined atomic coherence can therefore be created between randomly placed particles. Observation of photon echo on powders as opposed to bulk materials ope...

Transition metal ferrites such as CoFe2O4, possessing a large magnetostriction coefficient and high Curie temperature (Tc > 600 K), are excellent candidates for creating magnetic order at the nanoscale and provide a pathway to the fabrication of uniform particle-matrix films with optimized potential for magnetoelectric coupling. Here, a series of 0-3 type nanocomposite thin films composed of fe...

This paper describes the TE-TM mode conversion in a magneto-optical layer made by a SiO2/ZrO2 layer doped with magnetic CoFe2O4 nanoparticles. The mode conversion is caused by the Faraday rotation if the magnetization is aligned along the z-axis, parallel to mode propagation. The properties of this phenomenon are simulated using the full-vectorial beam propagation method (BPM). The simulation r...

The first experimental results on the functioning of liquid crystal cells doped with CoFe2O4 nanoparticles are presented. Transmission spectra in visible and near-infrared range, dynamic parameters Fredericks effect, refractive characteristics, as well wetting angles mesophase sensitized surfaces have been obtained. measured were K8 Crown glass, conductive ITO treated a surface electromagnetic ...

2014 Direct measurement of fluorescence quenching rates for various Pr3+ pairs in weakly doped LaF3 are reported. Since few pairs only are quenched, the transfer mechanism is short range. From the rate values, the shape of the fluorescence decay for heavily doped samples is predicted. The good agreement with the observed decay proves the interest of the connection between microscopic and macros...

The Photo-Fenton reaction is an advanced technology to eliminate organic pollutants in environmental chemistry. Moreover, the conversion rate of Fe(3+)/Fe(2+) and utilization rate of H2O2 are significant factors in Photo-Fenton reaction. In this work, we reported three dimensional (3D) hierarchical cobalt ferrite/graphene aerogels (CoFe2O4/GAs) composites by the in situ growing CoFe2O4 crystal ...

In this work the properties of CoFe2o4@ B18N18 have been illustrated as a novel catalyst to compare with well-known catalyst “Fe3O4@Silica”.It has been shown that CoFe2o4 magnetite particle can be use as important catalyst inside the B18N18 ring. In our previous papers amazing result about the BnNn properties have been calculated, exhibited (Struct. Chem., 23, 551-580, (2012); J. Phys. Chem A, ...
