“…The following increase of losses is determined may be by the rise of colloids concentration from 1014 cm3 till 1015cm3. This first experimental results confirm our assumption [9] about mechanism of retarding of silver colloids formation in superfine (lOnm -lOOnm) structure of fiber extruded from such solid solutions as AgClo.Bro.75. The multiple structure defects slow down substantially the interstitial silver diffusion in difference with easy diffusion in large grain size structure of AgCI or AgBr fibers.…”

“…For ecological and toxicological reasons the former fibres are to be preferred. Prolonged studies [1] have demonstrated that the best characteristics are achieved for the particular compositions AgBr 0.75 Cl 0.25 and AgBr 0.5 Cl 0.5 . This is why the present study concerns fibres of these two kinds.…”

The relation between the structure of fibres extruded from mixed silver halides AgBr 1−x Cl x and their IR optical losses and luminescence properties is studied. The recently established ageing effect of the considerable growth of mean grain size of the fibre's polycrystalline structure (typically from 20 to 1000 nm in two years) is correlated with IR and luminescence measurements. IR spectra measured in the interval 3.0-13 µm show growth of the concentrations of molecular impurities. The luminescence measurements are used for the characterization of the fibre's structure ordering. The luminescence decay kinetics is analysed theoretically in terms of the diffusion-controlled recombination of spatially well-correlated Frenkel defects. The considerable difference between the diffusion properties of monocrystals and fibres is established. This is caused by partial disorder (the grain structure effect) of the initially polycrystalline structure arising due to the fibre extrusion.

“…Among all the crystals being explored nowadays and used in the mid-infrared (IR) range, the ones based on solid silver and monadic thallium halide solutions have the greatest potential [1] . The former are represented mainly by the AgCl-AgBr system, which the flexible IR fibers are extruded from, and they are the only nontoxic polycrystalline fibers that can operate from 2.0 up to 30.0 μm [2][3][4][5] . They have found their applications in IR spectroscopy, laser diagnostic and endoscopic medicine, and laser cutting and welding, as well as in low-temperature pyrometry for night-vision fiber-optical system manufacturing [6][7][8] .…”

Crystals based on solid solution of Ag1?xTlxBr1?xIx for the manufacturing of IR fibers

et al. 2015

For the development of fiber optics for the range from 0.2 to 50.0 μm, one needs light-stable, nonhygroscopic, ductile crystals that would be transparent within this spectral range and have a lack of cleavage, and from which the flexible infrared (IR) fibers are extruded. The crystals based on solid solutions of silver and monadic thallium halides meet the conditions listed above. Consequently, by differential thermal and x ray analyses, we study the TlBr-TlI phase diagram using the crystals with optimal compositions, which we grow ourselves. We also manufacture light-stable nanocrystalline IR fibers that are transparent at longer wavelengths compared with AgCl-AgBr fibers.
