Usual structural hypothesis related to superionic glasses containing metal halides MY = LiI, NaBr, AgI, etc., implies the absence of chemical interactions between the host glass...

Lithium batteries provide the highest energy density which makes them ideal candidates for future generations of portable electronics and electric vehicles. The increasing...

Optical applications of chalcogenide glasses need a wide transparency window. Promising glass systems include HgI2. Our recent studies of the yHgI2 (1-y)As2X3 glasses, where X =...

A waste majority of crystals exists in several polymorphic forms in different domains of the P,T-diagram. Liquids and glasses also exhibit polyamorphism and the question remains...

Alkali halide sulphide and selenide glasses MY-Ga2X3-GeX2 (M = Li, Na, Rb, Cs; Y = Cl, Br, I; X = S, Se) are promising hosts for active and passive optical devices, solid-state...

Little is known on the structure and properties of vitreous Se doped with halogens in contrast to group III, IV, V, and VI dopants and also many metal additives. Our Raman...

AsxS1-x binaries belong to the most studied chalcogenide glassy systems. The glass-forming region in the system was found to be rather limited, 0.05 < x < 0.43, caused by...

Crystalline mercury sulphide exists in two drastically different polymorphic forms: red chain-like insulator, alpha-HgS, and black tetrahedral narrow-band semiconductor,...

Optical applications of chalcogenide glasses need a wide transparency window in far IR. Promising glass systems include HgI2. We have synthesised three vitreous systems...

PxSe1-x glasses cover almost entire composition range from pure Se to P0.84Se0.16. In addition, red phosphorus is usually also amorphous. The P4Se3 cage compound, situated in...

Lithium batteries provide the highest energy density which makes them ideal candidates for future generations of portable electronics and electric vehicles. The increasing...

Telluride glassy systems are widely used for phase-change optical recording. They are also promising materials for far-IR applications. The atomic structure of telluride glasses...

Non-linear optical (NLO) crystals are widely used in advanced photonic technologies for second harmonic and difference frequency generation (SHG, DFG), producing coherent light...

Japanese company TDK has recently developed a 320GB optical storage disc. In contrast to usual DVDs and BDs, the 320GB TDK disc seems to operate because of difference in...

Silica-free barium titanate bulk glasses, containing lanthanide elements, show unusually high dielectric response and a high refractive index. These properties allow crucial...

The ionic conductivity of sodium chalcogenide or chalcohalide glasses is 2 to 3 orders of magnitude higher than that of oxide glasses and comparable with lithium ionic...

Solid alumina Al2O3 has many industrial applications. Recently it was found that porous anodic alumina film formed by anodizing aluminium in an appropriate acidic/alkaline...

Heavy alkali halide sulphide and selenide glasses are promising hosts for active and passive optical devices. Lithium and sodium chalcohalide glasses exhibit high ionic...

Chalcogenide glasses containing light alkali and Group 11 (Cu, Ag) halides MY (Y = Cl, Br, I) exhibit high ionic conductivity while their heavy alkali counterparts show...
