Laser-stimulated birefringence of Ga2O3-La2S2.95Se0.05 glasses for optical recording of information

Results in Physics, 2019
We show an opportunity to change the birefringence of Ga2O3 – La2S2.95Se0.05 glasses doped by Er3+ and La3+ ions at λ = 1150 nm wavelength of cw He-Ne laser under illumination of the femtosecond laser.

3D Anodic Alumina Nanoarchitectures: A Decade of Progress from Foundational Science to Functional Metamaterials

Advanced Materials, EarlyView.
Ordered three‐dimensional anodic aluminum oxide (3D‐AAO) nanoarchitectures with longitudinal and transverse pores enable architecture‐driven metamaterials. The review maps fabrication advances, including hybrid pulse anodization, and shows how 3D‐AAO templates tailor properties across magnetism, energy, catalysis, and sensing.

Glass Transition Temperature and Mean Bond Energy of Chalcogenide Glasses in the As₂Se₃-GeTe-CdTe System

Inorganics
Chalcogenide samples from the As2Se3-GeTe-CdTe system were synthesized by the melt-quench technique. The surface topography of some of the samples was performed with the help of scanning electron microscopy.

The slope equations: a universal relationship between local structure and glass transition temperature

, 1998
In this article, we present a universal relationship between the glass transition temperature $T_g$ and the local glass structure. The derivation of the simplest expression of this relationship and some comparisons with experimental $T_g$ values have ...

A Colloidal Quantum Dot Thermistor and Bolometer

Advanced Materials, EarlyView.
This work introduces colloidal quantum dot thermistors employing a potential barrier structure to tune the activation energy of transport and hence the temperature coefficient of resistance (TCR). Upon integration with plasmonic absorbers, the CQD‐based bolometer device enables room‐temperature wavelength‐selective photodetection across the mid‐ to ...

Comparison of loss in silica and chalcogenide negative curvature fibers as the wavelength varies

Frontiers in Physics, 2016
We computationally study fiber loss in negative curvature fibers made with silica, As2S3 chalcogenide, and As2Se3 chalcogenide glasses with a fixed core-diameter-to-wavelength ratio of 30. We consider both simple and nested geometries as the transmission

Thin chalcogenide capillaries as efficient waveguides in the mid-IR - THz spectral range

, 2011
We present chalcogenide glass As2Se3 capillaries as efficient waveguides in the mid-IR and THz spectral ranges. The capillaries are fabricated using a double crucible glass drawing technique. The wall thickness of the glass capillary is properly designed
