In this work the comparative analysis of the thermostimulated luminescence (TSL) properties of various silicate crystals (undoped and Ce-doped Y2SiO5(YSO) and Lu2SiO5(LSO) single crystals (SC) and single crystalline films (SCF)) under excitation by alpha and beta particles, gamma quanta and daily light has been perfor…
We outline the differences between the nanocircuits derived from the dipole and the Mie theories, revealing how important a more accurate theory is in the derivation of the nanoimpedances of plasmonic nanospheres.
Large-scale research infrastructures offer unrivalled performance for the advanced characterisation of micro- and nano-electronic devices and systems. However, the access to large-scale facilities permitting this unique advanced characterisation is well known to be challenging and is generally incompatible with indust…
In this work fabricated p-Pb0.925Yb0.075Te:Te and n-Pb0.925Yb0.075Te thin films thermoelectric devices are composed of 20-pair and 10-pair deposited on a glass substrate using simple thermal evaporation method. Overall size of thin films thermoelectric generators which consist of 20-pairs and 10-pair of legs connected…
Self-assembled InAs/GaAs quantum dots structures with low temperature and high temperature cap layers are grown by meta-organic chemical vapor deposition. The effects of Indium composition of high temperature InGaAs cap layer on the structural and optical properties of quantum dots are investigated by the atomic force…
Electric and magnetoresistive properties of La0.6Sr0.2Mn1.2O3films deposited on SrTiO3(001) and LaAlO3(001) single crystalline substrates by magnetron sputtering have been studied. Characteristic features of the evolution of resistivity, magnetoresistance and Curie temperature upon the decrease of film thickness from…
Trap-limited conduction is here analyzed with special attention to chalcogenide materials used for phase-change memories. After a short review of existing theories, new developments are presented, based on very general microscopic assumptions. Electric field, carrier concentration, and electron temperature variable al…
Nowadays, nuclear industry is facing a crucial need in establishing radiological characterization for the appraisal and the monitoring of any remediation work.Regarding its experience in this domain, the French Alternative Energies and Atomic Energy Commission (CEA) of Fontenay-aux-Roses, established an important feed…
According to CISPR 12 an absorber lined shielded enclosure (ALSE) can be used if the results gained there match those obtained on an outdoor test site (OTS) [1]. Currently there are discussions on validation methods to be included in future editions of CISPR 12. One main problem for a systematic evaluation is the OTS…
We demonstrate entanglement between the vibrations of two macroscopic, spatially-separated diamonds at room temperature by means of off-resonant Raman scattering of ultrashort optical pulses and quantum erasure.
The method of field-ion microscopy was used to determine the threshold of nanopore formation in ion-implanted platinum. The threshold for ion-implanted platinum corresponds to fluence F = 10 17 ions/cm 2 . The size of nanopores is determined: 1–5 nm (transverse) and 1–9 nm (lateral, across the target depth). It is fou…
The cover picture shows a new colorimetric thin film assembly for studying bacterial biofilms as described by R. Jelinek and co-workers in their Full Paper on page 752 ff. The white background corresponds to a transparent sol-gel layer constructed through a dip-coating technique. Within the sol-gel are domains of poly…
We studied a plasmonic graded grating structure that can simultaneously generate third harmonic ultraviolet light of different wavelengths at different positions along the grating. Such broadband discrete ultraviolet generation is achieved through surface dispersion engineering.
The optical gap of Si nanocrystals strongly doped with phosphorus has been calculated. The energy levels of the electron and hole ground states in the Si nanocrystal were found as functions of the nanocrystal size and the P concentration in the framework of the envelope function approximation and under the assumption…

Thin metal films with subwavelength hole arrays (meshes) have been fabricated for operation as optical sensors. Mid-infrared spectroscopy and electromagnetic simulations demonstrate that free-standing meshes are particularly suitable for sensing solid nanopollutants.
Cover: Recent efforts to fabricate homogeneous optical nanocomposites based on transparent commodity polymers and nanosized pigment particles by in situ bulk polymerization are reviewed. Every single step of this scalable approach is examined in detail, with a special emphasis on atactic poly(methyl methacrylate) comp…
This paper reports the contamination performance of two distribution arresters (new and used ones) tested under three different contaminant conditions ? clean fog, ESDD (equivalent salt deposit density) level (A, B, C, and D), and kaolin contamination conditions, and their leakage current, total leakage current, and c…
Freeform lenses can be designed for diverse illumination profiles with good uniformity. However, most of the previous studies formulated for a single point source and the lens to design has a spherical bottom. In this study, the formulation is extended for multiple point sources and for lenses with a flat bottom in fa…
