Enhanced photoluminescence (PL) in a tellurite glass (TeO2–ZnO) doped with erbium ions (Er3+) and containing silicon nanocrystals (Si-NCs) is reported. The PL increase is mainly attributed to energy transfer from excited Si-NCs to the Er3+ located

The influence of halogen atom substitution (Br and I), in different amounts and positions in an aza-BODIPY skeleton, on the photophysical properties of some aza-BODIPY derivatives has been investigated by using density functional theory and its time-

An approach to electrical impedance tomography (EIT) data acquisition inspired by NMR-filtered back-projection imaging with fan isochromat distribution is proposed. A current projection is generated by injecting current at a certain point of the samp

We present results of the photorefractive properties of a chiral smectic A liquid-crystalline phase. In our approach, the mesophase is sandwiched between two photoconducting layers. In contrast to the effect due to the dielectric anisotropy typical o

A new solid state NMR Imaging method is presented. The method is based on the Redfield-Lee-Goldburg rotary saturation. The spatially encoded rotary line is observed step by step in the laboratory frame with a valuable signal to noise ratio and spatia

A new approach to solid-state imaging (SSI) is presented. The method relies on narrowing the resonance line using the Lee-Goldburg sequence. The technique is easy to implement in practice and may find widespread applications in materials science.

Two-dimensional 1H images of a solid obtained by magic-angle rotating-frame echoes are presented. The images have been reconstructed by processing the rotating-frame echo signals of a solid sample under the action of static and rotating field gradien

Switchable nematic emulsions are composite systems formed by liquid-crystal droplets dispersed in a fluid, homogeneous, monomer matrix. These systems can be switched from an opaque to a transparent state by application of a suitable alternating elect
